Use 3M™ Green Corps™ Hookit™ Regalite™ Sheets for shaping plastic filler, removing paint around damaged areas and scratch refinement of bare metal. The 3M™ Green Corps™ Hookit™ Regalite™ Sheet features a sharp, tough blended grain and is resin bonded for heat resistance. The 3M™ Hookit™ Attachment System lets operators quickly change out sheets during multi-step sanding processes. The open coat construction means that our abrasive grains are spaced so that dust and debris can collect in the spaces rather than loading the sheet. Additionally, the open coat feature provides an aggressive cut for faster results. These sheets feature aluminum oxide blended with 3M™ Ceramic Abrasive Grain for a durable and long lasting abrasive.
