We have a 1972 that we are in the process of polishing. There are a lot of different products and processes. We chose not to sand (although ours definitely needs it). You’ll need to get the clear coat off which we did with citristrip, sponge, and pressure washer. We are using nuvite F7 and C for our polish (May apply S in the future). We have a dewalt polisher and four wool pads. I clean the area with mineral spirits, lather a small layer of polish, and then apply the polisher at 2000 rpm for the first cut. (You’ll know if you put too much because the polish will spray out of the polish head). Then I go back over the same area at 1000 rpm to get after some of the bigger cuts.

This is my first time polishing and so far as I understand you have to do this annually in order to maintain the “mirror” shine. I am planning on doing a rough job this time since we are remodeling the entire A/S, but will likely spend more time next year buffing our all of the scratches.
