I tied clear powder today for the first time on some machined aluminum parts. I was expecting the same great results I always get will colored powders. But, the parts have terrible orange peel. I tried several experiments. Lighter coating resulted in smaller orange peel bumps closer together. Heavy coating resulted in a wavey orange peel. Coating the parts hot with a heavy coat gave the best results but the parts still have orange peel. If anyone has any suggestions I would appreciate the help.
