I have some small aluminum parts that will see a small amount of wear, and I would like to prevent surface scratches and the like as much as possible. I thought about powder coating using a clear powder, but I have not powder coating setup and would like to see if I can do something with what I have. I have read about home anodizing, but my big question is whether it hardens the surface at all, and if so, to what extent? The parts are 6061 and all I want is a clear finish. I have a large 12V power supply from an old electronics something or other that could be used for this, as well as buckets. The parts are no larger than 3"x3"x.5", so I don't think I would need tons of solution. If it will harden the surface, I may go this route. Any other thoughts would be greatly appreciated.
