Description

Just one gram of Extreme Liquid can lift and hold up to 8 tons; Ultimate Putty up to 4 tons.* Works on metal, wood, PVC, tile, plastic, glass, ceramic, concrete, brick, and more. Great for automotive, marine, plumbing, furniture, appliance, tool, and heavy-duty fixes—industrial uses too. Use indoors or outdoors. Impact, chemical, fuel, and heat resistant – up to 550°F (Liquid) / 350°F (Putty). Once cured, it can be tooled, shaped, filed, sanded, tapped, drilled, and painted. Easily fills large gaps and holes to keep your boat ready for the next adventure. *Lift and strength tests were conducted in controlled environments for demonstration purposes only. Attempting to replicate these tests is extremely dangerous and strongly discouraged. Do not attempt.
