Herculiner Roll-in Bed liner
I haven't finished this project since I need to address some rust issues up front, but I did do the back half and am very pleased with the results. Here is a picture of the back half after installation. It all has one coat, but the back half has had a second coat and looks much more complete. I sanded the area thoroughly before applying the Herculiner. You can pick it up at any Kmart for about $100 for a kit which includes one gallon of the stuff. I'll post more as I get further along.
