For over twenty years, LINE-X has brought a multitude of protective coatings products to market.  The very first product which is still the most common coating used today is Standard black LINE-X.  Standard black LINE-X is an aromatic polyurethane/polyurea hybrid with a higher than average tear strength, tensile strength, and temperature tolerance.  It's not only used for truck bedliners, but can be used as a protective coating on practically any surface including steel, aluminum, wood, most plastics, foam, concrete, fiberglass, etc.  Standard black LINE-X is good, but if you need better, we've go it!  Take a look at our Premium and Platinum coatings.
