Has anyone waxed an enclosed car trailer? They don't have carpaint and clearcoat on them. It is such a pain in the butt. Oh and mine is black. I usually use Paint Sealant on it a couple times a year if I can. It always leaves streaks. No, I don't think that I was putting it on too thick or not letting it dry long enough. I've tried butter wax also and wasn't much better. I did just get some new Americana and it worked really good. Anyone have any suggestions that have done these? I do it all by hand.
