[QUOTE=retransit;11623361]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.
This is why I posted a ? when I read "catalyzed lacquer" because I also remember back in the day when I was an automotive painter and was forced to paint with DuPont Lucite lacquer and had to deal with the exact same blushing issues with presence of any humidity, not to mention the crazing and checking found in lacquer finishes that followed in relatively short time spans compared the base coat clear coat systems of late.
