6" soft Abrasilk abrasive hook and loop discs with a revolutionary patented cloth backing that is laminated to ultra-breathable flexible foam. Compatible with dustless vacuum systems for a better, healthier work environment. The anti-clogging backing reduces the temperature of the work surface and enhances the resistance to clogging to grant a longer lifetime and finishing quality. Specifically designed for automotive paint applications, but also great for other surfaces/applications such as nonferrous metal, bronze alloys, steel, fiberglass, solid surface, hardwood and plastic.
