i ve tried to replicate a perfect factory polish using several grits, from say 320 -12,000. one after another, then with some high gloss rouge on two different material buffing wheels, and even some diamond paste. for some reason i can not, never could achieve the same results as straight from the factory. so i m very interested to see your results.
maybe my buffing wheels were getting too hot and causing some swirling or something. i am not sure
