Tim,
Excellent question my friend. I do on occasion I'll use gloss paints,But the problem I have here is very high humidity couples with high heat. Long story made short heat and humidity conspire to keep gloss paint from drying in a timely manner. Here in the South I have to thin gloss paint with lacquer thinner to speed the drying time,but still takes longer to fully cure than flats do.
Highest Regards,
Gregory Jouette
