FWIW: My airplane was painted with Dupont CHROMAPREMIUM automotive paint 12 years ago. The paint has held up superbly and the airplane still looks like it was painted yesterday.
To me, The painter is more important than the paint. A good painter can do miracles with cheap paint. A weak painter can make expensive paint look bad.
I built the full size mock ups of the B2 Bomber for the movie Broken Arrow at the Long Beach airport. They were glass and I ended up painting them with latex! Wonder if that would work on an RV! Ha!!
I've seen a few references to a Dan H. article on painting. Is it a sticky somewhere, or am I overlooking it?

I’m assuming this is what people are referring to.
