I have been tossing the idea of hard coat anodizing my al. frame around for a while, but recently have come across some much harder, more advanced options. The question is...does the frame have to retain any sort of electrical conductivity or could I use something that makes it totally resistant to any current? Not really sure if the electrical system needs to get to the aluminum for some sort of ground. I asked an auto mechanic friend and he wasn't quite sure either.
