I went a little over board on my last compounding & wax treatment to the point of reaching the gray primer. It's a small area above the rear passenger door handle slightly smaller than the size of a silver dollar.

I taped the area and papered around it and sprayed it with matching color. The spray coat looks several mils thick after removing the tape. Color match is good.

Now it needs finish sanding and compounding.

What proceedures, cleaners, paper grades & compounds etc. should I use to complete this process?

Color is standard MB black.
