I just did the Duplicolor stuff in my pickup and am pleased with the look, but am very sceptical of its ability to really protect teh bed. If you want to get good coverage on a LWB, plan on using at least 2 gallons. I bought a spray gun from Duplicolor to apply it and recommend that route instead of roll on, you want it to look even all the way around.

If it were me and I was going to use the truck regularly, I'd go with a professional install for durability. Quality costs $, but its almost always worth it.
