The photo I posted above of my 383 Road Runner wrinkle finish air cleaner I did with VHT and finished (heated) it with a Milwaukee heat gun. Yes I warmed up the metal with the heat gun, then painted it with the VHT and immediately went to it with the heat gun. It wrinkled quickly and evenly small sections at a time and never stopping until it was all wrinkled. I think it worked and looks okay for not being oven finished?
