As the subject reads...what is required to keep a machined finish looking like new? I had an aftermarket wheel on my last vehicle and the machined lip began to pit over time. Of course it was exposed to rock salt for about 5 winters. I've looked at alot of wheels that had either a machined lip or a machined part of the face. I'm hesitant to pursue making a purchase seeing that I will be keeping these on all year long, and thus exposing to rock salt again. Is it possible to keep them looking good given the environment they will be in?
