Last fall one of the guys at work gave me a hard time that my painted wheels looked dirty. Since I'm waiting for back-ordered parts for the motor rebuild, I've been busy polishing a set of stock Impala wheels. Hand sanding with 120, 220, 320, 600, 800 and 1500 grit paper. Then 3000 grit Perfect Cut rubbing compound. The final step was to polish with Simichrome. Depending on the wheel condition it took between 2 to 4 hours per wheel. I really need to invest in a power buffer.
