Being fairly new to the group, I was curious as to why I hadn't seen hard
anodize with a Teflon impregnation (a standard process) mentioned as a
possibility for the side wear surfaces.  There is a build up that is equal
to the depth of the anodize, but that is predictable and could be allowed
for.  I suppose Mazda has tried it as they seem to try everything.

I don't think anybody has tried it yet.

Sounds pretty good. Mazda has Teflon coated the porous chrome rotor housing
surface.
