Bondo® Glass Reinforced Filler makes an excellent foundation for hole, dent and rust-out repairs without the need for backing strips, cloths and resins. It contains short, interlocking fiberglass strands and fibers that make it twice as strong as regular body filler. It is also slightly thicker and provides a fast drying time, making the filler less messy on vertical surfaces like car doors.

Fiberglass Quality without the Extra Work
Bondo® Glass Reinforced Filler provides fiberglass-quality repair of small holes and rust-outs (up to 1/2") without the need for backing strips, fiberglass mat or fiberglass resin. This reinforced body filler contains short, interlocking fiberglass strands, making it twice as strong as standard body filler and much easier to use during vertical repairs. If your repair needs even more strength, it also works well with traditional fiberglass repair materials and tools.

Easy from Mixing to Sanding
The filler is easily mixed using the included Bondo® Red Cream Hardener, designed specifically for use with Bondo® fillers. It also features a fast-drying formula that is sandable in as little as 20 minutes, saving you time on auto body repairs.

For Auto or Marine
This waterproof filler is ideal for repairing dime size or smaller (up to 1/2") rusted-out metal holes and shattered fiberglass body parts. It is compatible with all paint systems for cars and boats.

About the 3M™ Body Repair System
Even a small repair can seem complex at first. So 3M's Body Repair System simplifies the entire automotive body repair process by dividing it into four stages:

  • Stage 1 — Prepare. This stage includes pulling dents, removal of paint and rust and efficient, effective masking of the area.
  • Stage 2 — Fill. This stage involves patching holes with reinforced filler and smoothing and shaping filler before painting.
  • Stage 3 — Paint. This stage includes painting the area and blending and smoothing primer and paint.
  • Stage 4 — Finish. The final stage for showroom-grade results: removing small defects, sealing and polishing clear coats and other painted surfaces.

3M supplies premium products such as abrasives, tapes, body fillers and tools for every stage. This system helps you work easily, efficiently and successfully across the entire body repair process.
