What kind of paint?

[ALAN GEDDES]

These things are just a little house on wheels. Treat them with a good quality exterior primer/sealer and paint. The Behr I used is 25 year house paint. It's better than the stuff on my house because I only needed a gallon. If you want a show car finish then sheet it with aluminum and paint it with automotive paint

I had wondered if a paint for decks, porches or such would be a good choice... since they must have some properties to withstand hot sun, rain, heat and cold...

I stated one time that I used exterior enamel over fiberglass on a small fishing boat that I built. Now, I remember that the enamel was porch and deck enamel. It adhered well to the fiberglass and held up very well for the 5 or 6 years I used the boat. In and out of the water, the paint did it's job. I agree that any good exterior enamel, latex or oil based over a properly sealed and primed plywood should hold up for some time. You can spend 4 times as much on a marine paint, but are you going to put your tear in a lake?
