I'm a big fan of Herculiner (
http://www.herculiner.com/ )
I coated one of my old van's floors with it, and the frame of my hose reel (Not the reel its self, that would have cut my hands up)
I couldn't make this stuff chip or crack off, and before I bolted the hose reel down it NEVER moved, even when I slammed on the breaks LOL.
Just make sure the surface you cover is CLEAN CLEAN CLEAN, using Acetone and something to really scour with.
Also be sure to use a high speed drill to STIR this stuff, the little beads settle to the bottom... and if you don't want the anti slip beads in the finish if your going to paint it on a hose reel, you need to thin it out a little with Xylene and strain it with a paint strainer.
After 3 years we stopped using this van, and a one day my dad hauling a 1100lbs diesel engine in the back scooting on the floor to make this stuff scrape off.
