yeah I got a professional undercoating gun from carquest paint supply, some bedliner material from a supplier in houston, and sprayed mine myself. Only cost aboot $150, which was enough material to cover 2# 6ft beds. Sprayed the bottom of my cab, and the interior up to the firewall and about a foot up the back wall. I have a single cab, but I ended up wasting about 1/3 to half of the material because the undercoating gun the company sent me, was one sorry POS. COuldnt clean it, so I though it was cleaned out, went to spray another large batch for the second coat underneath, and it was clogged, and cured before I could do anything about it. Otherwise I would have been able to spray atleast one coat in the bed as well. So I got a professional gun that can be broken down and cleaned thoroughly before I continued. It was pretty easy after getting ahold of the better spray gun, went on quick, thick and smooth. Maybe an hour of prep, and about 5 min to spray each coat. I would definitely recommend doing it yourself for the budget concious wheelers.
