Answer This Question

A:  It can work well, but if the boat runs onto the bottom, it can dislodge or wear it down.

    Q:We have a leak in our pool skimmer (underwater). The joint between the porcelain tile/grout & plastic skimmer throat contracts in the winter and then leaks. Is this the best product to seal this? Is it flexible after it dries for the weather change?

    Answer This Question

    A:  This item is ridged. Look to an RTV silicone for this.

          Worked great on trailer water tank
          I used this to seal my trailer's water tank that had split / cracked possibly because of a stone that hit it, and after sanding the surface very well and putting a screen mesh over the split area (crack was roughly 2 inches long in an "X" shape), applied the JB Weld and to it's credit the tank no longer leaks. Did this job last summer and camped twice this summer (2023), and so far NO LEAKS whatsoever. Highly recommend.

            Great stuff for aluminum boats
            This epoxy worked wonders to patch up my banged up aluminum boat to repair a couple tiny leaks and reinforce some impacted spots.

            Works for a lot besides marine
            I've been using this product for a lot of years for everything to boat repairs, house repairs, truck repairs, heck I even use it for epoxy bedding rifle actions in the custom stocks I build. Great for everything.

              Great stuff!
              I use this in all my boat repairs, hull, hardware repairs , almost anything and I like the newer product that dries white . I can’t say enough about how much I love the thick consistency after mixing and how fast it sets even underwater! Great product guys

                Ultimate repair compound
                Stupidly I overtightened a cast iron radiator fitting & PING! cracked it. Tried all the usual things like araldite to no avail. Marineweld and left it for a day, that was almost two years ago. Ten stars!
