## Description

Superior Repairs on Plastic Parts. This highly effective black two-part urethane adhesive delivers first-rate repairs on parts constructed of thermoplastic polyolefins (TPO) and ethylene propylene plastics notated on the part as PP, EP, TPO or EPD. An extremely fast work time makes 3M™ TPO Plastic Parts Repair an excellent choice for repairing nicks, gouges or small defects. The 1-hour cure time and 30-minute paint time increases productivity for follow-up steps. Use 3M TPO Plastic Parts Repair with 3M EZ Sand Rigid Parts Repair, PN 05885 instead of polyester repair products such as body filler or glaze. The Science of Better Auto Body Work from 3M. We put decades of development into our products for auto care and repair to help save you time and get the most enjoyment and value from the vehicles you own. Our 3M TPO Plastic Parts Repair is another great example of how 3M applies science to life and makes your life easier when it comes to making vehicles look their best. Use 3M Cubitron II File Belt 786F as high durability and long-lasting performance premium abrasive belt. It is ideal for tough detail work like cleaning, deburring, blending and finishing as well as working in small confined spaces. The 3M Cubitron II File Belt 786F is equipped with 3M Cubitron II Abrasives, which feature our Precision-Shaped Grain (PSG) technology with uniformly sized ceramic grains and precisely shaped triangular structures - essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface for the most efficient cut and even wear. Additionally, they fracture during use to maintain sharp abrasive edges resulting in a 30% faster cut and lasting 2x longer life than conventional ceramic abrasives. 3M Cubitron II File Belt 786F is available in various coarse grades and various widths as well as various lengths; it can be fitted on to various types of file belt machines available on the market. It helps to maximise productivity and deliver an efficient process in the workshop.

Review: My power file gets used almost daily & I've always been frustrated at how quickly my previous belts would wear out & break. I've only been using these new belts for the past couple days & they are worth the money. They remove material much faster & with hardly any pressure needed.
