Review on Erthree Glass Polishing Pads Kit - 34pcs/Set Deep Scratch Remover for Window Repair - Multifunctional Solution by Carlos Long

This kit was the same as the more expensive kits on Amazon. I had a severe scratch on my car window windshield, using a white roller on the edge I was able to reduce the deep scratch with a high speed drill. There are several videos on YouTube on how to do this. Keep the powder wet on the windshield and work in small areas. You can still see the scratch from the inside, but it's not as scary from the outside. Deep scratches can only be buffed out to make them less noticeable as the glass is made of two layers bonded together. Didn't get a lot of spatter, but I sealed the rest of the car with tape and paper. I only used a white roller and a scraper about 30cm long was worn off the roller.
