Use During the Fill Stage of the 3M™ Body Repair System
Even a small repair can seem complex at first. That's why 3M has developed the Body Repair System, which simplifies the entire automotive body repair process into four stages:

  • Stage 1 - Prepare: This stage includes tasks such as pulling dents, removing paint and rust, and efficiently masking the area.
  • Stage 2 - Fill: In this stage, you patch holes with reinforced filler and smooth and shape the filler before painting.
  • Stage 3 - Paint: This stage involves painting the area and blending and smoothing primer and paint.
  • Stage 4 - Finish: The final stage is all about achieving showroom-grade results. It includes removing small defects, sealing, and polishing clear coats and other painted surfaces.

3M provides premium products such as abrasives, tapes, body fillers, and tools for every stage of the Body Repair System. This comprehensive system helps you work easily, efficiently, and successfully throughout the entire body repair process.
