The 3M Bondo Fiberglass Cloth (00499) is a simple but super useful material for reinforcing body filler and making durable patches. Whether you're fixing a car panel, a boat hull, or even a cracked lawn chair, this 8 square foot cloth gives your repair job extra strength and structure.
Made from woven fiberglass strands, this cloth is stronger and stiffer than fiberglass mat, making it perfect for repairs where you need added support—like over rusted-out metal or damaged fiberglass. It works especially well with Bondo resin, bonding tightly to the surface and creating a tough layer that holds up over time.
You can cut the sheet to size, layer it for thicker repairs, and mold it to curved or uneven surfaces. Once the resin cures, you can sand it, paint it, or apply body filler right on top. It’s a great addition to any DIYer’s garage, especially if you’re into auto body work, boat maintenance, or household fixes.
Lightweight, flexible, and easy to work with, this fiberglass cloth gives you a pro-level finish without a big learning curve.
