Raft Trailer "plywood covering"
Getting a new aluminum snow machine trailer for hauling my big raft. It comes with a plywood covered bed. My instinct is to treat the plywood with some sort of weather proofing, but not sure of what to use. I definitely do not want to coat the plywood with something that is going to mare up the bottom of the raft.
Locally, I've heard suggestion to glue on outdoor carpet, treat the wood with linseed oil, or water proofing deck stain. Any suggestions on what I can use to treat/protect the plywood that won't mark up the brand new raft would be most appreciated.
I know the outdoor carpet is one option that would work for the raft, but the idea of gluing it on a trailer that will probably be sold and used for snow machines in a couple years is not appealing - the reason I'm considering alternatives to just treating the plywood.
