Marine sealant
Installed a swim platform on the back of my boat, this stuff works exceptionally well to seal the screws that I had to drill into my transom.

Best marine sealant on the market
This stuff is like welding, if you clean the material good and apply this stuff, its there to stay, I use it on watercraft and there is not a better product out there that holds a candle to marine 5200

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.

It works
Works pretty good easy to apply. Haven't had a chance to really test it yet. I used it to mount aluminum float pods on a aluminum jon boat. I used 1 tube per side. The dry time took a little longer because it was a sealed area.

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.
