Trim polishing

There are basically 3 different kinds of trim, stainless, aluminum, chrome plated.
Each requires a different process. Google is a great resource, but even there you will get better results with terms like polishing stainless, polishing anodized aluminum, etc..
A ground strap on your body ( ankle ) will prevent static shocks.
Nothing will prevent a machines throwing a piece of trim, chit happens. Be careful, Good luck
