I use Klasskote exclusively. I have to deal with humidity and lacquer (if you can even buy it anymore) blushes, as does dope. When I painted cars, I used a retarder and slow flash-off thinner in high humidity. Sometimes just thinner and retarder lightly on top of the color coats.

I've also never heard of catalyzed lacquer. It's a single part paint.

Here are pictures of my Fleet after painting. No primer used, just top coat color.
