I got my brother, Sean, a do-it-yourself spray-in bedliner kit for Christmas. He bought his 2002 Sierra new in late 2001 and we've wanted to do a spray in liner for it for a long time. We've been looking for a good-weather weekend and this one looked good so this project was our plan. Saturday morning we started by pulling out the bed mat and washing the bed out with Dawn dish soap...

I climbed in and chammied it off. The bed was still really clean. Mostly just some scuffs and scratches and a few small dings...

Then we pulled the tailgate and I started dissassembling it....

Meanhile, Sean and Dad got to work on scuffing the paint in the bed. We used red Scotchbrite pads. I've seen much coarser grit recommended, like as aggressive as 36 to 40 grit but this is what we used when we did the spray in on my truck eight years ago so this is what we did....

The card table I was working on seemed pretty rickety so once I got the tailgate broke down, I set up on a couple of milk cases with two folded towels each for pads...

Ok, my turn to sand....

I've said it before but I'm the Tortoise and Sean is the Hare. By the time I had the tailgate disassembled, everything bagged and tagged and the tailgate sanded, Sean and Dad were well into taping the truck up...

Here's a look at it all taped up...

This is where we broke for lunch. I had ordered Popeye's Chicken for everyone and had it delivered. During lunch, I expressed some concern that maybe we should wait a few hours for the sun to go behind the house, putting the driveway in shade before we went ahead and sprayed in the bedliner. The metal was really hot in the direct sun. It wasn't supposed to rain but when we came outside from lunch we could see Mother Nature had different plans....

On to plan B. We cut open the plastic on the driver's side of the truck and Sean backed the truck into the garage. Our garage isn't long enough to get the truck in and close the door, at least not with the work bench. We got it back to where there was maybe 30" between the back bumper and the bench. I put a bunch of loose stuff in the back of my truck (mop buckets, box of parts, etc.) to make room for the tailgate. We got it all set up in the garage without trashing much of the tape job....

I think by now, it was 1:30 - 2:00 and we were pretty certain it was going to rain. I was concerned what affect the humidity was going to have if it started raining while we were spraying so we opted to wait it out. It did go ahead and rain, and we even got some pea sized hail. By about 4:00 the sun started shining. Sean wiped everything down and we went ahead and started spraying. The sky soured again, even though it was forecast to clear off and it even rained a little but not enough to bring the humidity out of the 50's. It sprayed really nice. The kit I bought was Upol's Raptor Liner. I got eight bottles of the liner with the correct amount of hardener and it also came with Upol's schutz gun.

We ended up spraying about 7-3/4 bottles. Dad and Sean held up carboard on the sides while I was spraying to keep the material from spraying all over the garage. It turned out nice. I laid about three coats on everything and then at the end reached over the side and did a dust coat on the floor to make it look a little more uniform. I went about cleaning the gun and about 30 minutes after we stopped spraying, Sean started pulling the tape. It all came off nice...

I think by now it was pushing 6-6:30. We kept the truck in the garage until about 9:30 and then rolled it out in the driveway so we could roll the garage door down for the night. We were a little concerned about dew and what effect that might have but everything was fine. Here's what the truck looked like this morning...

We put everything back together this morning....
