Review on AUSTOR Sandpaper Assortment Automotive Furniture by Corey Katchem

I never write reviews but this sandpaper blew me away. I used it to clean my glass shower door after trying so many cleaners and nothing worked. I then used sandpaper and hardly had to oil my elbows and the hard water stains disappeared immediately. See photos! I used a 3000 grit sheet for the entire door and it looks like it could last. I don't think the sheet is even worn. I liked this sandpaper.
