After talking to both Line X and Rhino Liner, I went with Rhino on my 2000 GMC. Ultimately Rhino "sticks" on the bed much better because of the cold application. They also use more resin per square foot than anybody else. I did "over the rail" and am real glad I did. Mine was done in Kirkland at the junction of I-405 and 116th. They are in the phone book.
