anyone have tips on how to get into the nooks and crannies of parts? My current dilema is a set of 4 steel corvette rims. The rims looked great when they were picked up. Rally wheel silver is quite close to original. Unfortunatly when they were picked up it was raining and they sat in the back of a pick up for a day face up. Now they have rust where the hub is welded to the hoop. I’m thinking of preheating them to 400 and coating hot. Any ideas on how to get a hot coat gun to have a straighter path? I was thinking of machining the deflector to almost nothing, except to hold the tubes in.
