A Rhino bed liner is a sprayed-on permanent polyurethane finish meant to protect a truck bed from scratches, weather damage and corrosion. Spray-on Rhino liner may also be applied to flat beds, side steps, bumpers and grille guards. More than 4 million Rhino liners have been applied, as of 2015.
Several coats of Rhino liner are sprayed on to achieve a thickness of about one-quarter inch. Once cured, Rhino liner resists chemicals, dents and abrasion. Rhino liners are waterproof.
Rhino bed liner was introduced by Rhino Linings Corporation in 1988. In 2015, more than 2,000 authorized Rhino Liner applicators exist in more than 80 countries around the globe. Each Rhino liner application shop is independently owned and operated.
