There are a number of opinions on that topic. One thing I think
everyone will agree on is that epoxy is better than polyester resin. I
find pretty good deals on epoxy at http://www.uscomposites.com/

I have ripped out the floor out of my boat as it was pretty rotted.
Replacing it with plywood is not an issue, should I cover the whole
peice of plywood in fibreglass to stop it from rotting again, or is
there a paint/stain/sealer I can paint the wood with before I carpet it
that would be better and less expensive?

Thanks!
