I am use the eastwood hotcoat gun & seems that i am wasting alot of powder when coating something. Also seems i have to put alot of powder on the part to get it covered but still have bare spots. I have clean the ground strap to make sure i have a good ground. Ihave tried preheating & shot the part hot (helps alittle). is the other eastwood pro gun better ,am i doing something wrong, or is this normal.
