Ideal Choice for Larger Repairs Where Strength is Essential
Slightly thicker than fiberglass cloth, Bondo® Fiberglass Mat is recommended when additional strength is required on more severe repairs like larger holes and cracks. When used with Bondo® Fiberglass Resin PN 401, 402, 404 (sold separately), repairs are 100% waterproof, making the products ideal for automobile, tub, shower, sink, pool, hot tub, boat repair and more. This product can also be used on additional surfaces such as wood (PDF, 20.55 Mb), concrete and metal (PDF, 12.95 Mb) to provide extremely strong, durable and waterproof repairs.

Strong, Reinforced Repairs
When properly used with Bondo® Fiberglass Resin, Bondo® Fiberglass Mat reinforces repair areas and allows for repainting so that the repair looks like the original surface once the job is complete. Fiberglass mat is easy to cut to size and shape for customized repairs on automobiles. Fiberglass mat is often used with fiberglass cloth and fiberglass resin for repairs. Once the patched area has cured, it can be sanded smoothly so that it is level with the surrounding surface. A fiberglass repair completed with resin and mat is fully compatible with being painted.

Benefits of Fiberglass mat
Fiberglass mat consists of short strands of fiberglass bonded together with a resin. Fiberglass mat offers numerous other benefits. Fiberglass mat will not absorb moisture and is non-flammable. Our fiberglass mat is also resistant to most chemicals.

Repairs Customized to Your Needs
Our fiberglass mat is highly pliable, enabling it to conform to curved surfaces on automobiles. The flexible nature of the mat allows for customized automotive bodywork repairs on fenders, doors, hoods and other sections of the car body.

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.
