My local LHS didn't have any heat guns in stock. But I do have a "handyman" type made by Millwaukee.
The hobbiest guns are supposed to run at roughly 400 F. The lowest temp this gun will do is 750 F.
I've tested the gun on a wing tip on my Easy Sport 40, holding the tip of the gun farther away than normal. This seems to work.
But will too much heat cause problems with the covering later.[X(]
