Actually I went the cheap route, I couldn't afford line-x or rinoliner. the stuff I used is called Herculiner and is available from PepBoys, or Northern Tool. It was about $100.00 a gallon and comes with a "special" roller. I found it works best if you kind of dab it on with a brush. it goes on thicker and holds up better. It's not as tough as rino or line-x but it should hold up well to chemicals and salt water.
