Works well
This product does work well as a marine sealant. I used it on trailer bunk boards then covered the boards with marine carpet and it bonded the carpet to the bunk boards very well. The say it is not really used for that, but it seems to be holding up well. One thing, it does dry quickly so you have to have someone help if you use it on long bunk boards.

Great product!!
Ordered this to put the new frame on the top of my fish tank. It was super easy to to use, sealed the frame to the fish tank quickly and dried super fast. For the price, you can’t beat how great it works.

Great sealant against water
We have pool mechanical electrical components mounted on marine plywood., yet the top and sides of the wood were being affected by water and moisture. This fast cure product completely seals the seams of the wood, and nicely held paint to match the flat sections of the plywood. Great protection in a marine environment.

For pool skimmer use.
Had a leak in the skimmer area, sealed it like a charm, while regular epoxy failed. I will never use anything else again
