man, after re-doing my boat so many times, got tired of buying expensive plywood that didnt last but 5 years or so,
finally had enough and the last time i did it i fiberglassed the plywood before carpeting and upholstering everything. now is been over 8 years and everything is still as strong and sound as day 1. as far as paint with rubber in it i dunno, but i did see a cool matting that was just glued to the floor of the boat.
