The Bonding Component of Permanent Home or Auto Repairs
A secret: for common repairs around the home or shop, our well-known Bondo® products such as Bondo® Fiberglass Resin and Bondo® Metal Reinforced Filler are only as good as the hardener you use with them. Our Bondo® Fiberglass Resin Liquid Hardener is designed specifically to work with these products. The hardener is easy to dispense from its tube and chemically bonds with the resin or filler to create a fast-curing, easily-shaped material for a full range of home repairs. 

Use Bondo® Fiberglass Resin Liquid Hardener for a complete range of auto body repair, interior and exterior home repairs including tubs, showers, sinks, pools, hot tubs, boats and more. The cured resin is compatible with nearly any paint system including gel coat and marine paint. The filler is strong enough to anchor, drill or tap and provides a metallic appearance that won't rust.

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.

As a brand of 3M, Bondo is well known among boat manufacturers and collision repair professionals. This hardener – a crucial component for use with Bondo Fiberglass Resin and Bondo® Metal Reinforced Filler  – is another way that 3M applies science to life, and helps you restore and maintain the beauty and value of your cars, boats and other possessions in and around the home or shop.
