I'm building two very different style teardrops. One being an "off-road" style with high ground clearance and a tough exterior coating (spray-in bed liner). The other being more of a hot rod style with low to the ground stance and classic styling. Here are my two questions.
1.) If I spray my off-road teardrop with the Rhino liner / spray-in bed liner material, what's the best method to prep my plywood exterior to hold the spray material? My first thought was to take thin metal screen wire and staple it to the exterior of the teardrop. This will give the spray a "tooth" to hang on to. Thoughts?
2.) I'd like to use a nice wood grain plywood for the exterior on my "hot rod" style teardrop. I've heard that some folks use a marine grade varnish/shellac (Waterlox, etc) to seal the wood from rain and moisture. What would be your suggestion on sealing plywood that's exposed to the elements?

Urethane over the plywood I think would give you the look you want and the weather resistance you need on your hot rod trailer. If you are going to use screen wire over the plywood then cover it with a bed liner you will have to staple it all over or the wind will lift if off the surface causing it to flex and crack the coating allowing water infiltration and rot. I would seal the wood before covering it with screen. also I would consider some type of adhesive to secure the screen. I tried the screen wire thing back in the sixties with a roof coating over it on a truck camper I built and about two hundred miles from home I started seeing some small pieces of something sailing through the air in my mirrors, investigation soon led me to discover it was my roof coating chunking off. For your off road unit how about a good coat of urethane let it dry than scuff it and maybe a camo paint job over top. Or coat it with a fiberglass resin (available at most auto parts stores)and your screen wire to get a durable finish then coat or paint as desired. Use multiple coats of resin both under and over your wire.

I'm partial to epoxy with a UV protectant in it (and fiberglass).
