Urethane paint dries by chemical reaction not heat. I don't think you need them. Lacquer dries by evaporation and heat will speed the process although sometimes it causes problems too. If you're going to spray urethane just spray it in as dust free environment as you can and it will dry very quickly.

I don't know why you would need to cure the paint faster. Most of today's urethanes are buffable with an overnight dry. Dupont has two clears that can be buffed in less than two hours with 75* air temperature.

tooyou controll the 'drying of urethane by changine the reducer, NOT by adding heat. If it dries too fast it will be a nasty paint job.
Case in point, my mailbox. I painted it outside. The base coat and the flames look perfect but the sun got to it when I cleared it so there are millions of little bubbles in the clear. Looks great for a mailbox, but I'd be a sandin if it was a car!
