I am curious if anyone has ever/read about possibly taking there anodes of there drives and running them through a light sand blast just to remove the build up. would that return the anode to somewhat of a new condition exposing the new material?
I would think the area that the fastening surface contacts the drive structure would benefit from that to make a better bond. If the bolts and threads are white with oxidized goober pucky the current would be resisted...wouldnt it?
It's not a build up.It the zinc actually disentigrating or doing it's job.
You can buff,sand them but they'll just get ugly again.
Just cleaning the contact points will make them work better.
