Waxing the areas of your hull that are in the water at planing speed will
slow down your boat.
If anything you want to abrade that area.
As for washing the area covered by bunks.....the lake does mine for me as I
boat.

I just purchased a boat and wish to clean and wax the hull. It is on a
bunk
trailer. My question is - how do I clean/wax the areas of the hull that
are
under the trailer bunk supports and therefore not accessible for cleaning
while it sits on the trailer, or do I just not bother with those areas?
Thanks!
