yes you can heat the air dry stuff. the folks at NIC told me they do it all the time.. that said just about all we use is the heat cure..as it is tougher.. it's really not that hard to make a heat box. google around and you'll find quite a few designs folks have made for themselves.. mine is a wooden box with foiled foam inside lining the box.. we heat it with HF heat gun... easily reach 400 degrees if you need it, but we cure at 250 or so for a longer period of time ( 2hours)you also can now order direct from NIC and get all the colors they make.http://www.cerakoteguncoatings.com/
