      I used this stuff to patch holes in my bass boat. I pulled off old transducers and used this to patched the holes. Worked great. I put the product on a flat head screw driver and ran it right across the holes to fill them in flush.

          This product advertsies that it's for plastic fuel tanks and marine use. I attempted to seal a hole in a boat's fuel tank made of crosslink polyethelene. It did not even come close to adhering to the tank. The leftovers however did stick very well to my stainless workbench top! I would not recommend for fuel tanks. I called JB Weld and they said that it would not work. They told me to take it back to the store as they would not give me a refund. Luckliy the store did.

              I used this product to repair a 4 inch drain line in my basement, that had corroded due to age, I have used this product before to repair copper pipes. I recieved a free sample of this product at the sema show last year, I think this can repair just about anything

                  Comments about JB Weld Waterweld White Epoxy Putty:

                  I used it to plug 2 holes in my fuel tank while the fuel was still leaking from the tank. It stopped instantly. I didn't have to drain it at all. It didn't use very much and within a couple of minutes it set up. I didn't have to sit and hold it on I just covered the hole and smoothed it out and walked away. This stuff is great!

                      Yes, AnarchyMama! This JB Weld Waterweld White Epoxy Putty - Part No. 8277 should work fine on a overflow tank. Remove required amount of putty. Thoroughly knead putty with fingers to a uniform color. Press putty firmly to the surface to be repaired.
