The Liberty  Fiberglass Resin Repair Kit provides everything needed for complete and total repairs, from mending to priming. The thicker Fiberglass Resin available from CarGroom makes for faster, easier, waterproof, repairs on metal, fiberglass, wood and masonry. Great for use with fiberglass cloth or mat to fix rusted areas, holes, tears and cracks. The no-sag, no-shrink, and no-rot formula makes it ideal for custom molding as well. A one-quart can of fiberglass resin, 0.5 oz. liquid hardener, fiberglass mat (8 sq. ft.), plastic spreader, mixing stick and the "All-Pro Guide To Better Body Repair" are included under each translucent, pilfer-proof overcap and within the kit.
