Our Bondo-Hair Long Strand Fiberglass Reinforced Filler features strands of chopped fiberglass up to 1 long for extra strength on your toughest repairs: filling large rust holes, restoring shattered fiberglass and more. In fact, this waterproof filler delivers twice the strength of standard body filler, making it ideal for rebuilding missing pieces during full vehicle restoration.
Two Times as Strong for the Toughest Repairs
Formulated to be twice as strong as regular body filler, Bondo-Hair® Long Strand Fiberglass Reinforced Filler is suitable for your most challenging projects – rebuilding missing pieces, vehicle restoration, shattered fiberglass repair, filling metal rust holes up to 1” in diameter and more. 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 Hardener for 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.
