Yeah, IIRC, anodizing is just a form of oxidation, if that's the right word to use. I had looked into a home anodizing kit some time ago. All it consisted of is some chemicals, a bunch of buckets, and electrodes to pass an electric current through one of the solutions. I do know that lye gets it off PDQ. LOL.

I'm sure that the use of a quality thermal compound would help a lot. I only mentioned it because I had problems with all of my monster heat sinks in that the motor was always a lot hotter than the sink after a run. It turned out that the sinks were only contacting about 1/4 of the surface area of the motor that they should have. I had to do some sanding before I got a good clean contact and good thermal conductivity. Now, my sinks heat up with the motors.

I'm just asking questions. All in all, I like anodizing. It acts as an electrical insulator and could save the day in some situations.
