No need,
I think we are doing the same thing. Look I used to sand primer ultra fine, shoot color and would chip and flake off easily with normal landings. Sputter was a poor choice of words on my part. For final primer coat that I already sanded, I guess a better term would be shoot a light coat and not sand it. The sanding of the color coat is only like you state above and I fully agree if one is going to shoot the lacquer. If I were get the surface prep perfect and a light coat of primer looked good, I wouldn't sand, let it dry, shoot color and go from there. Sounds right? (Gee, a rational discussion here withoug screaming, flaming or insulting. Cool) :)
