Ideal for hatches, dashboard components, deck hardware, portlights and many other uses inside or out, it features a non-shrinking formula that forms a strong elastomeric bond and stays firm yet flexible even in tough environments.

It also won’t turn yellow over time, preserving the sharp, professional look of your boat or other watercraft. It won’t sag, making it easy to apply even on vertical surfaces. It requires no mixing and applies right from the container. This boat sealant becomes tack- free in as little as 10 minutes.

  • Perfect
Color: Clear Size: 3 fl oz Pattern Name: Sealant
This stuff worked perfect. I had a pin hole in my pool and as the water was spraying out I put this on my finger pressed it over the hole and it stoooed🤩 It holds up phenomenally!

  • As advertised
Color: Clear Size: 3 fl oz Pattern Name: Sealant
This product, works completely as advertised. Nothing adheres any better, above or below the Waterline. My only complaint (why I gave value for money only 4 stars) is that they don't make it in any smaller quantities. Often times, you just don't need 3 fl ozs. And once you open the tube, and the air hits the end, you can't put the genie back in the bottle. It's all going to harden, used on the project, or left in the tube :-( ... show more

  • Good marine grade silicone
Color: Clear Size: 3 fl oz Pattern Name: Sealant
Needed some marine grade silicone for some fittings on my camper and this worked perfectly. Put the cap on after you're done and the product doesn't cure in the tube and become a solid mess like some other products. The only thing which doesn't work well is the threaded screw-on dispenser cap. The thread will strip with too much lateral pressure, which always happens to me. Also, do yourself a favor and purchase one of those metal tube keys that help you squish material out of a metal tube. It will save your fingers from exessive squishing, lol. ... show more

This is some serious sealant. But the bottom end popped on me so be careful.

  • Fixed car leak
Color: Clear Size: 10.3 fl oz Pattern Name: Sealant
We used this sealant to seal some cracks in our Honda that were causing water leaks. This product was easy to apply and sealed the cracked that was causing the water leak. I would recommend this sealant as a cheap and easy solution for water leaks in cars.

  • Sealed water pump tubing to concrete fountain
Color: Clear Size: 3 fl oz Pattern Name: Sealant
I used the adhesive to seal a clear plastic tubing to a concrete fountain, supporting water flow through the tube and not letting water leak between the tubing and concrete. At 2 months there is no leak
