I polished my own rims, took about 6 hours. Removed tires, paint remover spray suitable for alum., taped off centre paint area. Sand polished area to be with various grades of paper up to 800 or 1000 grit. Buff with two compounds, the white rouge and the tripoli for the first rough polish, finish with the white rouge. Sanding takes the longest.Looks awesome and retains the shine.
