We used ACE RustStop instead of Rustoleum because I wanted a different colour. After 4 hot NM summers the paint has faded a few shades (realized just how much when I touched up a spot). I will clean, sand, prime and paint the bus again with a latex paint (probably Behr's Marquee as I hear great things about it) once we get a home base to park on. I am thinking of adjusting my colours a tad. I think the bus is too light and I want to get rid of the rub rail colours. I followed the tips on the above links (forum has a lot of good info) and did not sand between coats. I refused to sand 40 ft of bus in 90F to 110F temps. Also, I do not recommend panting anything at those temps. I had no choice. Read, research and figure out what will work best for you. Any flaws in the rolled on paint jobs are difficult to see with a camera. You have to be real close to see them. I have tiny runs from the spray job and cracking bondo from the previous owners showing thru my paint. The bondo will all be removed once we install baggage and access doors. Just remember, as with any paint job, prep is everything.
An alternative view to the $50 Paint Job is a "how to spray" which is great if you are someplace where you can spray without spraying all the neighbours stuff.
