I have an older enclosed trailer that the floor is starting to show some age in it. It is plywood and was originally painted grey. The wood is in good shape for the most part, but a lot of the paint has started to wear off and I'm looking for something to put back down over it. I've been looking into some of the deck and concrete restoring products, but a lot of the reviews say they start peeling up after about a year. I've heard of guys getting the floors done with spray-in bed liner. With a 8'X32' area plus the door I think that would get fairly expensive to do. What else have people done?
