401 Fiberglass Resin, Polyester, 1 Pt.

Bondo Fiberglass Resin Model 401 is a strong polyester resin engineered for automotive, marine, and general repair work. This versatile material bonds to multiple surfaces including fiberglass, wood, metal, and masonry, making it ideal for patching rust-outs, rebuilding damaged areas, and creating lasting structural repairs on vehicles, boats, jet skis, and RVs. Whether used alone as a sealer or combined with fiberglass cloth and mat for reinforced repairs, this resin dries rapidly and hardens to a durable, waterproof finish that resists chemicals and solvents.

The 1-pint bottle is compact enough to store in any toolbox, and the material can be sanded smooth in less than two hours. Once cured, it accepts nearly any paint system, including gel coat and marine paints, allowing seamless finishing.
