I have used it on a boat, It is thick and a little bit hard to work. At the time it cost more per quart than regular enamel was for a gallon.
Outstanding paint. I used a roller to apply it, after blowing all of the loose stuff free of the roller with a compressor. It started out showing the nap pattern, but quickly laid down to a very smooth finish. I had a couple trouble spots from new paint over half-dried paint. I used a brush dipped in thinner to smooth it down.
My first choice for an RV would be to spray auto paint, but I have had trouble spraying lacquer outdoors, and it always seemed to need a lot of wet sanding. I guess the catalyzed stuff is still di-isocyanate or something like that? Dangerous stuff. Brightside would likely be my choice.
