Dear Roger ,,, please send me the piece of paper with the $2,500 on it.
Address it T Wentworth, bottom paint job.

Make sure to sign it, and have it show the name of your bank nice a clear.

Thanks, for your help.

By far, the best and approved method for a boat about the size I recall
Tom talking about is a piece of paper about 3" x 5" properly printed by a
bank with about $2,500 written on it:)

As most of you know, I'm a real do-it-yourselfer but some things just
aren't worth it.

I looked at a boat this past weekend. There must have been twenty layers
of bottom paint. It was so thick, ....

I'm thinking ??? ,, how on earth does one get this bottom paint off.
Sanding will do the trick but I would think it might take a month.

What is the prefered method of bottom paint removal? What tools to use?
Is there a bottom paint removal substance?

After the bottom paint is removed, right down to the bare gelcoat ...
about August 1st .. joke there ..

After the bottom paint is removed,, what should be done? Put a thin coat
back on? Put on a coat of the sealer stuff?

Bottom paint doctors wanted ,, calling doctor Scrape, Sand, and Remove ,,

Well, so far I don't see anything in the thread better than the method I
last used, two guys with sharpened (and resharpened and resharpened...)
3/4 inch chisels scraping their brains out. It took us about three long
days to do a 33ft sailboat.

I don't think it was twenty layers, but it was pretty thick and very
hard work. Two teens we tried to hire to help couldn't hack it. They
couldn't figure out how to scrape off the paint in any reasonable amount
of time.

Most professionals use a heavy scraper if the paint is really hard and
brittle. It's a tiring job, but can be quicker than applying softener, as
the paint flakes away in large chunks.

And be sure to get a scraper with a carbide blade. They out-perform
steel by a mile, especially if you don't an easy way to keep
resharpening the steel.

Actually, I just saw a better method, if you will. Don't scrape it off.
Take off the loose stuff and paint over it.

How did you avoid gouging the ****e out of the gelcoat?

Push scraping, steep angle on the chisel blade, a piece of cardboard
between the back end of the chisel and your hand to hold down the
bruising, and it wasn't much of an issue.

I still think sodablasting is going to be a better way to do it. The
problem with just scraping the loose stuff and then painting over it
all, is that eventually, the stuff underneath lets go... and if it does
so in a large enough chunk, you'll end up with a big section of
unpainted bottom...and that may be asking for trouble.

Roger's right. I didn't have $2,500, so I went part way with my 26
footer. I paid to have the old paint soda blasted off for about $25/Ft.
It removed the old ablative and the barrier coats, and exposed all the
blisters that had been hidden.

I then spent 50 hours digging out and filling blisters, finish sanding
the entire hull, applying 3 barrier coats and 3 ablatives. It was very
rewarding but I'll never to it again. Next time I'll have it blasted
and inspect it thoroughly after blasting, blister repair, barrier and
ablative coats and pay for all that.

Good luck!
Mike

I don' know where you are, but in the upper Chesapeake I hired a
fellow who had a scraping tool he developed. Took 20 yrs of bottom paint
off a 33 ft sailboat I bought for a cost of several hundred dollars.
Took him about 6 hours to do it.

I had tried the gel peel approach and found it a real mess and not very
effective. This approach was a bargain and no where near as abrasive as
blasting.
