Review on 3-Piece Diamond Polishing Compound Kit (4000, 8000 & 50000 Grit) For Marble, Glass, Metal & More - 10% Diamond Powder USA Made by Fredo Zhan

I ended up washing my wife Garmin and it left scratches all over the titanium and sapphire glass. I thought we would need a new watch.I got the 4,000, 8,000 and 50,000 kit. I also purchased a Variac clone to control the speed of my Dremel and Drilax felt polishing pads. Using a Dremel tool at slow speed, I started with the 4,000 and it took less than 5 minutes to see the scratches gone!I then worked up to the 8,000 and the watch started looking better than new. I then used the 50,000 and the titanium and glass really were polished.I finished with Meguiars NXT liquid wax and the watch glass looked perfect. I didn’t remove all the fine scratches from the rear titanium body as it’s not necessary and are only noticeable because it’s polished. When it forms it’s oxide layer it won’t be noticeable.This was fun to use. Use circular motions like when you detail a car with an orbital tool so you don’t create hot spots. Also check the temperature of the glass every 30 seconds so you don’t end up damaging it. I highly recommend this diamond paste.
