Assorted Macro Grits: 3 Very Fine 120 + 3 Fine 100 + 3 Medium 80 + 3 Coarse 60 Macro grits are a class of abrasives that range from very fine to coarse sandpaper calibers. They feature mid to low grit numbers. Macro grit-sized sandpapers are commonly used on tougher wood and metals and have a stronger clearance. Three to five 9”x11” sheets of Dry sandpaper are designed to be used with the various soft rubber sanding blocks or DIY wood/plastic blocks or glass sheets. The soft rubber blocks work best for contoured car body surfaces, while wood blocks or glass sheets are best when you desire a true flat surface finish (e.g. Finish polishing an engine block when installing head gaskets). The sandpaper is held in the rubber blocks using steel gripper teeth, while staples or spray adhesive is used with wood, plastic or glass sheets. The Dry Course to Very Fine grit sandpapers can be used from the rough of stripping paint to metal to final feather edging around the repair area, as well as shaping and sanding body filler. The Dry grit sandpapers are used during the initial Stage 1 of the 3M Automotive Body Repair System, while the Fine to Very Fine ‘WetorDry’ grits are use in the final Stage 4 of 3M Body Repair. The abrasives are long-lasting tough and resist loading. Designed to be used on wood, metal, drywall, fiberglass and painted surfaces. Use for hand or machine sanding.
