Blisters 'n microwaves
 
I may have talked about this idea before but it was inspired when I was
doing blister repairs on a boat and used a heat gun. The heat gun
literally drove water from the hull and it poured out of adjacent
blisters so...........Why waste time heating the glass when you really
want to heat the water and other polar molecules. Enclose the boat in
a cover of aluminized plastic and put a microwave generator inside.
The water and other polar molecules in the gel coat would be driven out
over a few days. Of course you'd have to keep the power level low
enough to not cause arcing near any metal fittings but that should be
easy. You might want to score the gelcoat to facilitate the
evaporation of the water.
Next, you drive thermo-setting resin into the gel coat under pressure
or even slowly setting ultra-low viscosity epoxy. Finally a sealer
coat. No BS gel coat peeling that fails 80 % of the time.

Fair enough. So how are boat loan interest deductions devoted only to the
*rich* as you earlier claimed?

Even my twenty foot runabout cuddy would have qualified for the credit
before I tore out the sink, ice maker and alcohol stove. Regardless, I paid
cash for the deal and do not qualify.

Do you now understand my point?

What are the other heating possibilities other than microwaves that

I think the application of too much "heat" can cause more harm than
good, the glass gets moist over time then as you've seen then you
effectively boil the water the expansion (by about 600-800 times by
volume) creates considerable pressure enough to force water out some
distance away.

Clearly there was a path there originally but how much did that excess
pressure open it up or delaminate the layup even more???

It seems to me the best way to remove moisture from osmosis effected
glass is to use an electronic moisture finder (they have them specially
for GRP & most boat surveyors have one in their kit) that way you can
draw the shape of the moisture then limit your drying activities to that
effected area only. Drying causes damage no matter how you do it, by
heat, by grinding, by peeling etc.

As for the microwave idea I guess it's possible however you'd need huge
power to heat a boat hull even a not so big one. A tiny domestic kitchen
microwave which is properly shielded, insulated etc, has the beam
directed precisely at the target, has the target rotate so the tiny beam
can get at all of it over time & they use bulk watts with lots of loss.
I guess another consideration might be any other water in there??? with
a boat, even small amounts if boiled when enclosed, could again generate
huge force & consequent damage??

It's a loopy idea on first pass, but not that much more so than some
others that people have spent huge amounts on. The hull peeling is
another as far as I'm concerned.

I suspect the problem with microwave is that the "cavity" or metal shielded
enclosure needs to be tuned to the microwave frequency wavelength, otherwise
little heating will take place and the standing wave ratio will destroy the
microwave generator.

Induction heating? Nope - needs to be a metal.

Big ass oven? Maybe - wouldn't need to set the temp too high to dry out
water, but might require a long bake.

I know! A scanning CO2 chemical laser! You could program it to scan the
whole hull, similar to the prop measuring systems, except much higher power.

I watched a guy finish the edges of saw cut, 4" thick bluestone by spraying
water from a mist spray bottle until the edge surface of the bluestone was
saturated, then immediately heating it with an oxygen/acetylene torch.
Bluestone is very porous and absorbs the water. The torch then heated the
water very rapidly so it boiled and converted to steam before it could drain
out of the bluestone. The water basically "exploded" in a micro way,
leaving the bluestone edges with a natural, weathered, micro sandblasted
appearance.

That is probably a very real concern in my opinion. Turning water
into steam can create some very high pressures if entrapped.

The best cure is simply not to buy a boat with an osmotic blister

owners of boats, and others with a stake in the used boat business, but
better osmotic acne remain *their* problem, and not yours.


Easy to say but the real world is different if you own an older boat.
Boats that have never blistered in the past can suddenly develop a
crop if conditions change, e.g., water temperature, length of season,
etc. On a boat over 4 or 5 years old you really have no recourse with
the manufacturer.

The vast majority of blisters affect only the gelcoat and do not lead

considerable damage. Best advice for those with cosmetic, gelcoat
blisters is to forget about them and enjoy the boat. It's appropriate
to check for any sign of delam during the periodic haulout, whether
there are cosmetic gelcoat blisters or not. It would be hard to imagine
that the cosmetic benefit of a microwave approach would outweigh the
potential damage to other portions of the boat.

chuck,
Do you not recommend popping the blisters, allowing the blisters to dry out
and applying an epoxy coat? That doesn't sound exotic, and I thought it
would be prudent for any boat that is kept in the water.

Such a "surface" treatment is about all the trouble the situation
really warrants.
And anybody who convinces a boater to stick a boat into a "drying tent"
and spend $1000's in lay days (or lay weeks) to cure blisters should be
ashamed.

One of our local yards does a very good job of blister repair. Their
process involves a peel job and then the application of a few layers of
vinylester laminate under a new barrier coat. They put a lifetime
warranty on the process, and in ten years they have had only one or two
boats back for a re-do. They are the local exception.

Most blister repairs fail. Some sooner than others. The good news is,
for the vast majority of blisters there is absolutely no reason beyond
cosmetics to deal with them at all. 99% of the time they are out of
sight below the waterline.

I had a batch of chine blisters that I dealt with two or three bottom
paint jobs ago. Just sanded them flat, let them dry for a few hours,
faired them out, and slapped on the bottom paint. Cost was less than
$100. I fully expect to see those same blisters back again some day
(but maybe not)........and if I do I'll spend another $100 to deal with
them. That's much better than spending $10,000 or $20,000 or maybe more
to deal with them and *still* having them reappear in the future.

Delamination, of course, is another and very serious problem.
Blistering does not "progress" to delam, although in very rare cases
blistering may be an indication of an underlying delam problem. Got
delam? You're going to have to deal with it whether you see blisters or
not. Got blisters without delam? No big deal. Taking a drastic course
to remove them would be like spending $20,000 to have a surgeon remove
a benign mole from your butt cheek- it isn't hurting a darn thing and
almost nobody will ever see it.

The microwave concept is really a pretty neat idea at first look. An
improvement might be to just treat the blisters and surrounding area. No
need for a screen room. Just a directional microwave. They do it for
termites, just monitor the temperature, to avoid superheated areas, that
would explode. use the mw to heat the water up to a simmer. Might even be
a good way to check for osmosis. Moisture meter is not going to really
check for water behind an area of good gel coat. It can not sense the
water, and if it is a density checker, extra resin or glass is going to
change the readings. mw the hull and check for hotter spots. Like Chucks
blisters. Use the mw to accelerate the drying. Would be cheaper than
vacuum drying. A lot less time. Or use it in combination with mw and
vacuum drying.

I'll never do this cuz I have waaaaaaay too many other weird projects.
It came out of a scheme of mine to measure the fluid level in oil wells
using microwaves.
I have done a lot of looking into blister repair and even have done
some of it. What I find is that blister repair is mostly a scam that
fails about 80% of the time. As others have pointed out, blisters are
really only a cosmetic problem. I have NEVER heard of osmotic blisters
causing hull failure on a boat made from woven fiberglass. I HAVE
heard of severe problems in hulls made from short strand mats. If
anybody has ever heard of a hull failure or accident resulting from
Osmotic Blisters, i'd like to hear about it.

Thanks

I don't know how you would fix a blister without removing the deformed
gelcoat.

Gelcoat ( essentially a layer of tinted resin) is somewhat porous. You
may be thinking of a barrier coat, not the gelcoat. When the term
"osmotic blister" is applied, the osmosis is the passage of water
through the gelcoat, not through the laminate. Plastic doesn't absorb
water, so if there are no voids in an FRP hull it isn't ever going to
become "waterlogged".

When I refer to "fairing", that's the same process you describe above
with the filler.

My thinking is backward from yours, Chuck. I think of the gel coat as the
layer that is supposed to be waterproof. The laminate may or may not be
waterproof depending on how well the layers are saturated with resin. I'm
sure if you scrape the gelcoat off something like a BayRay or other mass
produced boat, you will have a leak.

I read his essay and I don't think that I said anything that needs to be
amended.
Pascoe did say that both the gelcoat and roving/mat are porous. I don't know
if this is true of modern resins but the older boats made of polyester resin
were somewhat porous. But not to the point that you would notice significant
accumulation of sea water in the bilge. I had an old Reinell once that
leaked about 2 quarts a day. It wasn't coming from the engine room nor way
forward. It had to be coming from under the cabin sole. I cut an inspection
port into the sole and found a spot where water was oozing in drop by drop
right at the center of the keel. I didn't see any cracking so I decided to
leave it as is until haulout time. After removing several coats of bottom
paint I found that the gel coat had been worn off . Probably from repeated
beachings at one time. My fix for that was a few layers of cloth and epoxy.

I would not let any crack or gouge in gelcoat go unrepaired. Particularly
under the water line.

I think we would agree on that. Particularly since it's almost
impossible to crack or gouge *only* the gel coat. :-)

Your experience with the leaking keel is a good example. After several
groundings, you noticed some water seeping into the bilge through the
keelson. The couple of layers and cloth you applied for a fix went well
beyond a simple gelcoat repair.

I think you could strip all the gelcoat entirely off a boat and it
would still float. If the fibers were adequately wetted out with resin,
the hull wouldn't even absorb water (or "wick" it around). That seems
to be where we disagree.

As you know, there are some premium manufacturers who don't even use
gelcoat on their fiberglass boats. If the mold is perfect enough, one
can get by with paint rather than gelcoat. Gelcoat is an easy
workaround for imperfectly finished molds, as it tends to hide various
sins while paint tends to magnify them.

That isn't exactly what I said, but after removing the bottom paint, the
area sans gel coat was smooth and I didn't know if any of the laminations
had worn off. Being a belt and suspenders kind of guy, I chose to build the
area up a little. I probably could have gotten by painting the spot with
epoxy.

Now you are qualifing with "adequately wetted out with resin". Sure some
better hulls will be more resistant to water penetration. The cheaper hulls
still depend on the gel coat to keep the water out.

:-)

When one states that water is going to leak through the frp laminate
and into the boat unless it is somehow stopped by the gelcoat- and if
one means "if the hull is defective.......", then it would be best to
so state. When talking about general functions of gelcoat, laminate,
etc it would be customary to assume one is talking about a standard
hull rather than a defective one.

No builder depends on gelcoat to keep water from leaking into the
bilge.

Not true.


Cracking is one thing. Gel coat can (and will) crack easily. Gouging is
another issue, given than most gel coat applications is thinner than a dime.
Making it thicker is no good as it will tend to crack more.

Here is an idea. Why not address questions presented to you in other
threads you started before starting yet another new thread?


Jim, are you just looking for a fight? My gosh, you posed the question,

"For the rich????????"

Was that really supposed to be more than rhetorical?

You're trying with Harry, now you're trying with dhohara. Why not knock it
off?

Jeeeesh!

Thanks Mom.

BTW: He posed the statement about the deductions being only for the rich.

Have a nice day John.

You should ask yourself why you facilitate both of these newsgroup
troublemakers.


How absolutely funny.

Look in the mirror lately Krause?

BTW: Everyone has a bad day every once in a while. I did indeed get into
with Harry the other day but I did so only to set his lies straight.

Funny that you never commented on his troll and continued arguing.

Regardless, I recall you having a bad *month* with calling Harry a word I
shall not repeat with every post you made to him.

My point is that we all have our bad days John and you being my netmommy is
not appreciated.

I think you could strip all the gelcoat entirely off a boat and it
would still float. If the fibers were adequately wetted out with resin,
the hull wouldn't even absorb water (or "wick" it around). That seems
to be where we disagree.





Now you are qualifing with "adequately wetted out with resin". Sure
some
better hulls will be more resistant to water penetration. The cheaper
hulls
still depend on the gel coat to keep the water out

******

:-)

When one states that water is going to leak through the frp laminate
and into the boat unless it is somehow stopped by the gelcoat- and if
one means "if the hull is defective.......", then it would be best to
so state. When talking about general functions of gelcoat, laminate,
etc it would be customary to assume one is talking about a standard
hull rather than a defective one.

No builder depends on gelcoat to keep water from leaking into the
bilge.


Gee Chuck I think that's a bit of a statement. Most fibreglass
laminates are pretty porous if there are no barriers.

I'm not saying water would "flow" as such, but certainly it will seep
into the glass & definitely damage it over time.

On the other side if anyone did actually wet the layup enough that it
was truly water "proof" then it would be a very weakened laminate,
overly heavy & expensive waste of resin.

The best fix thus far is a good outer barrier usually of vinyl ester
resins in conjunction with a tissue tie layer. Even inside you need
flowcoat or such to stop the laminate being too porous from that direction.

I don't comment on Harry's troll and arguing because that's what Harry *wants*.

Yes, that's true. I apologized for it, and it has not been repeated.

Understood.

JimH,
You can see that Harry will continue to troll all of us anytime he wants to
get a rise and start a good argument. We all need to just ignore his
trolls.

Sometimes it is best to take the advice of experts.Subject: 3.3 The
destructive Troll

In about the year 1999 a new breed of Troll appeared who
have the declared intention of destroying a specific Target
newsgroup. This is done by a variety of posts, (see
Section 4) intended to drive normal posters away from the
specific newsgroup.

When the percentage of Troll posts, including followups
exceeds about 75% of the total posts, most readers seem to
just give up and unsubscribe. Subject: 5.1 Ignore them and they will go
away.

This is the traditional usenet method of dealing with
Trolls, and is regularly suggested.It is similar to the method use to train
dogs, and very
young children, ignore bad behaviour and reward good
behaviour. Thus it is only likely to work if the, The Infant
or Attention Seeker theory, is true

No offense, fellas, but, really, it's a bit too much of "do as I say," not
"do as I do." Hardly a day goes by here without both of you directly or
indirectly insulting others. Perhaps you need to stand and and say the
following here every day:


1. I am powerless over trolling-my life has become unmanageable.
2. I believe a power greater than myself has made me this way, and I
am not responsible for my behavior. Harry is responsible.
3. I have made a decision to turn my will and my life over to the
care of RepubliGod as I understood him.
4. I have made a searching and fearless moral inventory of myself, and
discovered that I couldn't count...

And so on.

Stay tuned for the next installment of the The Reverands.

have gone (one, two, 10, 30) days without insulting anyone."

I can't argue this point with you. I don't know what the hell you are
talking about.

I got a kick of how the Rev kept butting in when you & John were
awkwardly starting negotiations on a boat deal.
He must think John just fell off a turnip truck. After all John is
probably one of the few here who has seen Yo Ho up close.

I'm talking about your position that damaged gel coat will cause a
fiberglass hull to leak,
(based upon the premise that the function of gelcoat is to "waterproof"
the fiberglass).
