DIY Glass Scratch Removal Kit 3" (75mm)

Did the job perfectly

Used the polish and supplied wheel to remove a scuff mark in the very middle of a 1 M square window. 20 minutes of easy work and it was gone.

Tried to use this kit to take out scratches on a door lite. The first stage worked great. But it left me with a frosted pattern. Steps 2 and 3 made no impression of it whatsoever. Worthless.
