I was wondering does any one use powder coat as a filler. Coming from an auto body back ground it goes against my grain to NOT put some kind of prime or filler on the surface before you top coat either paint or PC. I have done a few jobs that needed some help and I have sanded them out before recoating them and have had great results. I have even put very heavy coats over hammered out dents and sanded them smooth and had great results. I have noticed that fillers like Lab Metal leave repair rings. For these I have coated with powder and sanded out and then hot flocked for great results. Has anyone done similar things, and any comments on the use of Metal to Metal would be appreciated.
