This wasnt planned, but worked out well. I was lifting the rear rubbermat for totally unrelated reasons when i found a ton of surface rust and some holes. So it turned into a full strip of the interior. The tub is sprayed with Al's Liner Heat & Noise Reducer (HNR) and their spray-in bed liner. I stripped all the factory sound deadener off the floorpan. It was already cracking & peeling, and i was afraid if i sprayed over it, it would contine to peel, and the bed-liner would lift off the floor. An air-chisel makes quick work of this, but i recommend dialing back the air pressure so you dont damage the floorpan. I (poorly) masked off the interior and sprayed the HNR. It has to be sprayed down with an undercoat gun to prevent clogging; (i used Al's spray-gun). Overspray is a real concern. Do a better job masking off the vehicle than i did. I did two coats of this, one day apart. It took about 1.5 kits to do the two coats, but its worth it. Dont skimp on this step! A couple days later i shot the spray-in bed liner. I had my compressor regulator set to 40 PSI, and sprayed the whole tub with 2 kits. I recommend a third; i ended up thin in a few spots, altho it wasnt obvious at the time. Next time i will use 3 kits. Dont forget to pull the masking tape off a soon as youre dont spraying, otherwise it will begin to cure to te tape. Also, youll note little tape 'sticks' sticking up thru all the bolt & screw holes; this was a ton of work, but made it super easy to find all the holes later. They pulled right out. Totally worth it. I let the truck sit in a heated garage for two days to cure (it was december when this was done), and it probably couldve used one more day; i found a couple soft spots while putting the interior back together. The end results? Its awesome. The combo of two coats of HNR + the bed-liner, its damn near as quiet inside the truck as it was with the full interior. Very happy with the finished results. You can follow along with the bed-liner job in my build thread over on FSB, starting here.
