Green Corps™ products are made with a blend of abrasives including 3M's high performance ceramic abrasive grain which provides increased abrasive life and a faster cut rate when used on plastic filler. D and E weight backing makes these abrasive products extremely durable for sanding paint, metal, or fiberglass. Open coat construction reduces loading on fresh filler. Products are available in no-hole and dust-free configurations, with either Stikit™ or Hookit™ attachment. These 6 inch 3M™ Green Corps™ discs are used for stripping paint to metal, shaping and sanding plastic filler. Suggested backup pad 05776. The 36-grade, 6 inch discs use the Hookit™ attachment system.
