I tried them all...3m kit, mothers mag polish, and then toothpaste -ultrabrite old fashion white goo...I was pretty impressed about 70-80% better than beforehand....this was all hand rubbed so I can only imagine with a buffer results would have been better yet. one thing I noticed was when the tp was drying/hardening it had an incredible resistance on my cotton towel. iow, I had to use some serious elbow grease to get things going...but overall very happy with the positive outcome and dirt cheap too...
