I just redecked my snowmobile trailer. I did a bit of research and ended up using 3/4" Marine grade plywood primed with a 3-2-1 Primer and painted with Waterproof Behr solid stain. A lot of research i found recommended products like Behr Deck over or Rustoleum 2x deck paint etc. I have had much bad experience with these types of 'paint' on wood as they tend to peal up and flake off. Knowing that I would have tracks and skis sliding across the wood I opted for the route I did. I can't say it will be much stronger if any but if it adheres I will be happy. So far this season I have spun track enough to leave rubber on it without any sign of pealing or even wear just rubber. So I am happy so far. Also want to mention 3/4" is pretty stout so consider your spans on the frame might be able to go with a 5/8" or maybe even 1/2" oh and Marine grade is expensive... at least in 4x10.. so if your deck is 10' long something to consider.
Thank you for the tips and the heads up. For longevity purposes, I wish I didn’t have to go with wood but it is the most cost effective method even if I have to replace it 5 years down the road. I’ll definitely look into the coatings that you recommended here. Do you have any links you could share?
