The word "diamond" describes much more than the Diamond-tough, industrial strength polyurethane, hybrid and polyurea coatings that make up Diamond Liner spray-on bed liners. The resilience and symbolic commitment of a diamond is reflected in all aspects of the long successful, family owned automotive aftermarket business.

Diamond Liners, Inc. was founded in December 1990 by John H. Bender and his father, Houston O. Bender. The company quickly became established as industry experts and became a bed-liner market leader. In 1995, the company expanded into manufacturing and distribution of equipment and chemicals. In 1999, Diamond Liners invested in a new 11,247 square foot standalone facility featuring environmentally safe and AQMD approved spray booths for chemical test sprays and in-house protective coating applications. In addition to the booths, the new facility features many other high tech components of Diamond Liner's complete system of equipment sales, service and support. Also in 1999, the company became an authorized distributor for equipment manufacturer Graco. It also works with BASF, one of the world's largest raw material and systems supplier.
