a person I now was using that stuff for their boat. Suppost to be better that POR. If you go to their web sight they have a link to tests done in enviromental conditions where the bullet seems to hold up well.

I will take a look at their website. I just saw the stuff on Ebay. That was the first time I had heard of it.
