I'm painting 15 small frames (9 x 12" Sanded Poplar 1" x 1" deep) with Black Glossy Nitrocellulose Lacquer. I made them all from the same wood stock, milled the wood the same, sanded the same, etc, etc the same. I'm painting them all at the same time, same conditions, same paint with an Accuspray HVLP system which is working very well for me. Why would two of them have crazing on them? And, it's not crazing everywhere, just in small spots. I tried photoing them for you, but it's not easy photographing black lacquer. Anyway, here are two photos of the same leg on the same frame - 1/2 crazed and 1/2 smooth. I'm still getting wood grain showing through, but figure a couple of more coats should solve that. So far I've got a coat of lacquer black primer and four coats of topcoat on it. What gives?
