Unlike sandpapers made with aluminum oxide, Gator Ultra Power Premium Series sandpaper is made with zirconium oxide allowing the product to sand three times faster and last three times longer than regular sandpaper. It’s sharper, harder, and cuts faster, and holds its cutting edge longer. The product is available for belt and orbital sanders, and comes in various grits. Cost: $5 to $20.
