Yes heat guns suck for motor use lol. My buddy melted his carb insert on his motor using a heat gun and the one time I attempted to use my heat gun at the track I shut down everyones chargers who were plugged into the same track outlet....so a good 15-20 peoples power was shut off cause of my heat gun. That was the first and last time I took that to the track. I now use my comp heat....works much better.
