We built our teardrop 3 years ago. It is all wood. We coated the entire thing in 3-4 coats of epoxy along with one sheet of fiberglass fabric. After a ton of sanding, we then applied 4 coats of marine spar varnish. We re-varnished last year. we will probably redo next year, just because we did a crappy job and i don't like how it looks up close. I am pretty picky. We may go with clear exterior paint base if the tests that others are doing work out well. I did the epoxy fine, even though i had never done it before, however, applying the varnish is a struggle each time. I get runs.
We store our trailer inside at all times except when we go camping. I have examined it pretty close and do not have any failure at any point that I see. Without epoxy, you would probably need to revarnish each year. I know that is what Roly Nelson does. Doug Hodder uses clear car paint product I believe, over epoxy, and does not require as much upkeep.
For us, wood was the way to go, we love the look, even with the upkeep.
Oh, and we have been rained on a lot, as well as snowed on. No failure of the finish so far.
