Re: bottom paint 1, me 2, all done, test
Thanks for your post in the other thread pointing here.
I have an '87 Oday 35 (it would be interesting to compare HINs), and am about to go through the same process.
Last year, I sanded the bottom with 80 grit, and applied 2 coats of WestMarine CPP in the spring. All looked good when I splashed. However, after she was hauled, the paint started falling off. It appears as though the original bottom paint (no one knows how old) continued to decay, and flaked off - in big chunks. Right now I have about 3 square feet where I can see the original Gelcoat (it looks good too!).
