Bondo Fiberglass Cloth
Fiberglass Cloth for Professional-Quality Repairs
Bondo Fiberglass Cloth is perfect for any size job, large or small. The fiberglass cloth is a versatile repair material for use on automobiles, boats, tubs, showers, sinks, pools, hot tubs and more. It works on a variety of surfaces, including metal, fiberglass, and wood. Strong woven cloth is cut with scissors for uniform repairs.
Bondo Fiberglass Cloth provides structural reinforcement for stronger repairs and must be used with Bondo Fiberglass Resin PN 401, 402, 404 (sold separately). The product repairs holes, cracks and gaps. When used with Bondo Fiberglass Resin, repairs are 100% waterproof, making the products ideal for tub, shower, sink, pool, hot tub, boat repair and more. Bondo Fiberglass Cloth is slightly thinner than fiberglass mat, making it easier to work with and easier to hide when finishing. This product can also be used on additional surfaces such as wood, concrete and metal to provide extremely strong, durable and waterproof repairs.
Reinforced Repair Areas
When properly used with Bondo Fiberglass Resin, Bondo Fiberglass Cloth reinforces repair areas and allows for repainting so that the repair looks like the original surface once the job is complete. Fiberglass cloth is easy to cut to size and shape for customized repairs on automobiles. To complete the repair, you'll add layers of fiberglass cloth along with fiberglass resin to fill the hole. 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 cloth is fully compatible with being painted.
Benefits of Fiberglass Cloth
Fiberglass cloth is a woven fabric that helps reinforce repairs with its high strength to weight ratio. Use this fiberglass cloth where resin alone would not provide sufficient strength. Fiberglass cloth offers numerous benefits, including a resistance to expansion or contraction as temperatures change. Fiberglass cloth will not absorb moisture and is non-flammable. The fiberglass cloth is also resistant to most chemicals.

This fiberglass cloth is highly pliable, enabling it to conform to curved surfaces on automobiles. The flexible nature of the cloth 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.
- 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
Product measures 25.5 X 47 inches rectangular. Some have said that this is a heavy cloth but in the world of fiberglass cloth this is really a light to medium weight. It came folded so close and tight that at the fold corners the weave has separated. See attached pic. So if if doing a layup of several layers this is really not much of a problem. If however you are doing a finish cover to be exposed to the view of the world like my present use it is detracting since it has these weave separations in about a 5 X 5 inch pattern over the entire sheet. If this is your case you might try to find the cloth which comes off a roll.

I used it to make my initial shape for a custom fit 12" subwoofer in my car. It worked fine, air bubbles are a little harder to get out from the woven fabric material however.
It's fiberglass...

Woven thin layer, so if you want something solid it'll take you 3-5 layers (depending on flat/curved area).By Michael on September 8, 2022

Perfect for smaller jobs, worked okay for a dashboard repair.
By Colt on February 25, 2022
I wanted something thin to reinforce the old dashboard. It was a bit difficult in the creases but that’s common for all small radiuses. It did the trick!
