Devcon Instant-Mix Epoxy Dries in 1 MinuteThis 60 second glue is a must for every race day tool box. If your Pinewood Derby car breaks on race day, this glue will get you back on the track almost immediately. We have personally repaired cars that breaks in two during their heat and get them put back together before their next heat. This is a high-strength 2-part adhesive in an easy to use instant-mix applicator… just squirt and stick. Final bond is high strength and weather, water and solvent resistant. Fills voids and bonds uneven surfaces.
