Review on 🪚 Dura-Gold Premium 6" Gold PSA Sanding Discs, 10 Each of 80, 150, 220, 320, and 400 Grit - Total of 50 Self-Adhesive Stickyback Sandpaper Discs for DA Sander, Sanding Automotive Car Paint, Woodworking, Metal by Christopher Gonzalez

Update: 80 and 150 grit lasted about 4 car panels. 220 and 320 grit about 3 panels and 400 grit about 1.5-2 panels (depending on size). I'm deducting the stars from 5-4 for that. I wish the little grains lasted longer. Dura Gold is as good as any! Don't hesitate to recommend it to a friend. BUT! A few application tips: 1) Make sure to clean the area of dirt from time to time 2) KEY POINTS when sanding down existing paint: Clean the disc of old paint/dirt. I like to use 91% isopropyl. Spray a sufficient amount of product onto the grinding wheel on the grinder and leave it on for 10 seconds. Then run the grinder outdoors, away from the workpiece, or in a container. This will clear it of any debris.
