I use a heat gun rather than stealing the wifes dryer because I did get in trouble for that LOL..But pretty much as wicked said. Bare in mind though if your going to use it to dry out uros. Still give it time to flash off normally as per the instructions. You don't want to dry it to fast with a heat gun, once the its flashed off (Normally about 20 minutes) then by all means dry it further with the gun to assist some curing, otherwise you could create a seal too quickly and as the thinners try to evaporate off you may capture them under the skin of the paint and create an issue..Its rare that I do actually use a heat gun as I have got too close a cple of times and overheated the paint and bubbled it so be wary. If anything I use it to warm up the panel a bit on a really cold day (When I know I shldnt really be painting) so the uro isn't going onto cold metal. Really the airflow of an airbrush is generally sufficient to dry your paint, if you go on a bit wet..GL
