Expanding Your Capabilities in Do-it-Yourself Vehicle Repair
Bondo® Fiberglass Cloth Tape 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 Tape 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 (PDF, 20.55 Mb), concrete and metal (PDF, 12.95 Mb) to provide extremely strong, durable and waterproof repairs.

Reinforced Repair Areas
When properly used with Bondo® Fiberglass Resin, Bondo® Fiberglass Cloth Tape reinforces repair areas and allows for repainting so that the repair looks like the original surface once the job is complete. Fiberglass cloth tape comes in convenient 4" width, ideal for smaller repairs and for reinforcing seams. You can easily cut it to specific sizes and shapes 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 Tape
Fiberglass cloth tape features a woven fabric that helps reinforce repairs with its high strength to weight ratio. Use 3M's fiberglass cloth tape where resin alone would not provide sufficient strength. Fiberglass cloth tape offers numerous benefits, including a resistance to expansion or contraction as temperatures change. Fiberglass cloth tape will not absorb moisture and is non-flammable. 3M's fiberglass cloth tape is also resistant to most chemicals.

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.
