Hello out there! I have spent the last year taking the mutiple layers of paint of the decks of my sailboat. The deck is 3 layers of 5/16" plywood then covered with cloth and West Epoxy. As the boat was new to me in 1997 with 15 years of use I fiqured that if I was going to renew I''d do it right and remove every piece of hardware and get back down to the Epoxy base and at the same time inspect the wood for signs of water damage. Luckly, I found very little. I don''t suspect any movement in the substrate as the cause for the cracking and chipping of the old paint. I suspect the paint and or the applications by previous owner was flawed. I''m not sure what was used for paint previously but it was extremely hard. So hard in fact that sanding with a random orbit using 36 grit pads was such a slow process, I ended up using paint remover. I have contacted the West System people and they suggest that I use Alwgrip. The problem is its'' best applied by the "Pros" and sprayed.I need to do this my self and that means apply by brush. Seeing that the previous paint did not stand up very well, for what ever reason my QUESTION IS What would you use? A one part polyurethane, which is an easier application, is a little softer and (less apt to crack) and resign to the fact to refinish more often Or a two part liner polyurethane which is a more involved application but harder (maybe more prone to cracking) and supposed to have a longer life. I don''t want go through the laborous job of removal again. Anyone out there with a similar situation Thanks

I''m a little confused. You said that your boat has 3 layers of 5/16 ply (total 15/16?) or do you mean a three ply 5/16 inch plywood. You said this was cloth covered. Is this a wooden boat? If so go to the Wooden Boat web sight (www.woodenboat.com)for advice. If you are down to plywood on the deck don''t use polyurethane. Put a layer of Dynel set in epoxy. This is what I would have thought the West System guys would have said. This makes me think that I do not have a true picture of what you have.
