3M™ Hookit™ Abrasive Sheet 740I delivers uniform, consistent finishes every time for higher quality automotive body repairs and restoration. Our purple abrasives are 3M's best performing class of abrasives. These abrasive sheets sand faster to improve productivity and reduce cycle time, while improving consistency for higher quality results. E-weight backing and unique premium mineral blend combine to make these sandpaper sheets extremely durable. The reusable 3M™ Hookit™ attachment system allows automotive body technicians to use the entire life of the abrasive sheet, resulting in less shop waste. Our versatile abrasive sheets may be used on a variety of sanding surfaces, including clear coats, fiberglass, filler, metal, paint and plastic. These sheets are available in either no-hole or dust-free configurations to maximize productivity. The no-hole abrasive sheets are recommended for stripping paint or sanding marine fairing compounds. The dust-free sheets excel at stripping paint to metal, shaping and sanding plastic filler. These sheets may be used for either machine or hand sanding in dry sanding applications. These sheets feature a unique mineral blend of aluminum oxide. We chose aluminum oxide abrasive, which is a popular choice among industrial professionals, because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges. Due to its fast cut-rate, hardness, and strength, it is widely used in automotive bodywork applications. Our best performing class of 3M purple abrasives will pay off with a longer life, faster performance, more consistent results and higher quality repairs that reduce rework.
