I needed to put another coat of gloss paint on the Stinson I am working on. It was in my drying box (I use enamels and built a drying box to shorten lengthy drying time). Usually I take a model out of drying box well before I paint it, and it is at room temp by time I paint. Yesterday I tried an experiment. I got paint and airbrush ready before I removed fuselage from drying box, so it was still warm when I began painting. It seemed to work well that way. it seemed like there was less of a tendency to run, and I wanted to get a very wet coat for good gloss.
I say warm rather than hot, as my dryer runs at about 105F, but it did seem to make a difference.
