Gorilla 113442 0.85 fl. oz. Epoxy Ultimate

Gorilla Epoxy Ultimate is a high-strength two-part epoxy made for tough repairs when you need a durable, permanent bond. It is Gorilla’s strongest epoxy formula, with a bond strength rated at 4250 PSI, and it bonds to many common materials including metal, concrete, ceramic, PVC, fiberglass, wood, and many plastics. It also sets in about 10 minutes, so it is a practical choice when you want a repair that starts holding quickly without a long wait.

For DIY projects, this product is especially useful because its no-sag formula helps it stay where you put it, even on vertical or awkward repairs. It is designed for indoor and outdoor use, helps fill gaps, cures black, and can be sanded or painted after it cures. Full cure takes about 24 hours, and Gorilla notes that it is not recommended for polyethylene, polypropylene, vinyl, or rubber.
