I just saw this duplicolor bedliner online and it comes in aerosol cans. Its alot cheaper, I was thinking about spraying the inside of my jon boat with it, maybe fix a little leak i have. Anyone dealt with it or heard anything about it?

I used it inside my boat and it worked great.

Smoother then herculiner and easier to clean once applied since it doesn't have the nooks and crannies.  Just follow the prep directions to a T and don't take any shortcuts and it works great.  

My whole truck is painted with it, and I love it.  However, I tried it on my casting deck, and as great as it held up, it was hot and I experienced more foot fatigue than when I had carpet.  Plus it was slippery when wet.  For the $30 at lowes, I would get carpet.
