Tired of Body Filler Hardening Too Quickly?

YES!! For us guys whre life if HOT! or tying to prime/paint outside,YES use the HF temp gun and see how hot that metal is!!!!!!!!!
And I have found the best time to shoot is right at daylight, when the dew is still on to keep the dust down, and no bugs.
I have everything prepped the night before, so all I have to do is wipe the car down, fill the paint cup. Yes I am shooting in a garage.
