Anodizing does not involve anything "mechanical"...correct? Its bathed in a solution of some kind with a current running through it. I don't see how it can fail in that process.
I've called before. I'm calling tomorrow with my specific question.
The anodizing process involves (2) basic steps. First the part is 'etched'. That is basically an acid bath. It removes all surface impurities and opens up the surface so it can accept the dye in the second step.
Second step is the actual anodizing. Part is in a chemical bath. Current is applied through the part and throughout the bath and a dye is added.
The acid bath step is the part that has caused concern for people wanting to re-anodize their cranks. They are concerned the acid will attack the epoxy resin.
For those wanting to fully explain anodizing..................feel free.
