Works very well with Dremel polishing wheel
As some other reviewers have denoted, when you use this with a Dremel tool polishing wheel on the slowest speed, it made rather quick work of correcting the chemical damage and a couple of scratches on my G-Shock G7900-01 Mineral Crystal. Careful manipulation perpendicular to the scratch took out moderate depth scratches such that unless you really know they were there, you have to manipulate the crystal under a bright task light to see any residual signs. I didn't have to use the Finish polish on the G-Shock crystal as it was swirl free and nearly perfect after three small applications of the Repair polish. Keep your hand cupped over the polish wheel, or it will sling the polish everywhere. Also, AVOID making contact with the plastic bezel as the polish wheel will mar it. I also used this on my IPhone 11 Pro Max screen and removed medium scratches. Not as successful as the watch crystal but good enough to not have to have a new screen replacement. Well worth the results on my go-to EDC watch versus searching for a replacement crystal, which I could NOT find and/or a service bill or a new watch! I never attempted usage of the provided wood push tool, nor would I have the time, patience or satisfaction with manual results, hence the 4 rating.
