Two Times as Strong for the Toughest Repairs

This filler features durable strands of chopped fiberglass up to 1" long, eliminating the need for backing strips, mats or cloth. For repairs where even more strength is needed, these added materials can be easily used. The versatile filler is suitable for repairs on fiberglass, metal and wood.

Easy from Mixing to Sanding
Bondo-Hair® Long Strand Fiberglass Reinforced Filler is also very fast and easy to use. The filler comes with Bondo® Red Cream Hardenerfor fast, easy mixing. Its fast curing properties allow for sanding in as little as 20 minutes, keeping auto restoration projects on schedule. The cured filler is compatible with most fillers, primers and paints.

Use During the Fill Stage of 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.

Customer Reviews
Bondo® Hair Long Strand Fiberglass Reinforced Filler is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Sets way too fast I have used this in the past with good success however the last two cans I bought were unusable due to the product kicking off way too fast. Conditions were ok, shop was cool and product right from the store. After a fast mix I couldn't even get it out of the mixing lid before it was thickening up. I tried an extreme small amount of hardener and still no luck (less then 1/3" hardener for a golf ball size amount). Maybe it's all a bad batch, not sure but beware!!
