I just did mine with Grizzly Grip this weekend.
You can get it in a wide range of colors. It took the better part of a day to prep, roll two coats, and re-install seats and harware. I used the package of 1 gallon and 3 quarts (4x8 truck bed kit). It was about $130 with shipping and about $30 for other supplies (MEK, tape, paper, scotch pads, 4" roller, 2" brushes for corners and edges, beer). The people at Grizzly Grip are very helpful. Prep work is the key to a good final product.
I'll try to post a couple of photo's later.
