Line-X also has a line of products that can be poured onto horizontal surfaces. It can be applied thicker than standard spray-on Line-X and is self leveling to create a smooth, rock-hard surface. It was designed as a wearable surface to protect the inside of dump trucks so their loads do not wear out the metal and rust. Used this way it can wear down over time, but can easily be reapplied for additional years of protection. We have found that is has many uses. Not sure about how tough this stuff is? Come on in for a nice demonstration involving a very large sledgehammer.
