Fiberglass Resin Repair Kit with Fiberglass Mat (Quart)

Patching a cracked fender, rebuilding a boat hull, or fixing a fiberglass body panel all start with the same thing: a solid resin and mat combination. This US Chemicals kit gives you everything you need in one box to get the job done right.

Inside you will find a quart of fiberglass resin, liquid hardener, four square feet of fiberglass mat, a plastic spreader, a mixing stick, and an All-Pro Guide to Better Body Repair. The resin itself is thicker than typical formulas, so it stays put on vertical surfaces without sagging or running. Once cured, the repair is waterproof, impact-resistant, and ready for sanding and finishing. It bonds well to metal, fiberglass, wood, and masonry, making it useful beyond just automotive work.

For best results, prep the surface thoroughly before applying. Clean off any loose material, rough up the area with sandpaper, and lay down the mat before saturating it with the catalyzed resin. The cure time is relatively quick, so mix only what you can use within a few minutes.
