My first thought is to try it. I like my torch and I like my extinguisher even better. I couldn’t find an answer to the flammability question online after searching for a bit. My thought is that a heat gun won’t start it on fire, but might alter the poly—perhaps in the form of making it cloudy. Your best bet is to give it a try (with extinguisher on hand and probably using breathing protection in case it starts producing noxious fumes) and see what happens. If you’re happy with the results, you have your answer.

Update:
After searching some more, I’d say you’re better off contacting the manufacturer for their dry autoignition temp. Your heatgun can get up to 680F and the liquid autoignition temp is 450F. If you use your heatgun on the liquid, it will combust!
