Polishing TPI Runners...
I am wondering what can be used on the runners and top of the TPI unit on my GTA to polish it up and make it look a bit more presentable. I was thinking of trying Never-Dull on these parts to try and shine them up but am unsure if that's a safe way to go.
Anyone have any ideas or thoughts?
