Use During the Fill Stage of the 3M™ Body Repair System
Even a seemingly small repair can be complex. That's why 3M’s Body Repair System simplifies the entire automotive body repair process by dividing it into four stages:

  • Stage 1 - Prepare: This stage involves tasks such as dent pulling, paint and rust removal, and efficient masking of the repair area.
  • Stage 2 - Fill: Patching holes with reinforced filler and smoothing and shaping the filler before painting are the key steps in this stage.
  • Stage 3 - Paint: Painting the repaired area and blending and smoothing primer and paint are the main activities in this stage.
  • Stage 4 - Finish: This final stage focuses on achieving showroom-grade results by removing small defects, sealing, and polishing clear coats and other painted surfaces.

3M provides premium products, including abrasives, tapes, body fillers, and tools, for each stage of the body repair process. This comprehensive system enables you to work easily, efficiently, and successfully throughout the entire process.
