UPDATE!!!
After I finished building my Tamiya High Lift, I had some momentum built up, so I had to keep charging. I brought my custom built 1.9er outta storage and started up on it again.
It hasn't seen much use since Unimoger's competion last May, and I wanted to get back on it. Here it is before I tore it down to start my next round of additions, upgrades, etc.
The Silverado body started out as a beater that I had mounted on an electric chassis that I just beat around with. I had holes drilled in the bed and the hood for standard mounting. The body now mounts to the frame via screws that are located on the underside of the frame. Anyway, the holes had to be fixed, along with all the rock rash, so that's where I started:
I ground the holes out underneath and feathered them out on top with my dremel. Then I sanded the top to prep them for filler and primer. Underneath, I used plastic epoxy and little plastic patches to cover the holes. Mmmmmm...remember kids, don't intentionally concentrate the epoxy vapors and huff them, as it may fack you up!
Next, I filled the holes from the top with body filler. While I was at it, I ground off the bullshyte on the roof. The body had OnStar and XM antennas molded on it. :roll: In the scale world, I do believe you'd be a puzz if your 1.9 crawler-trail rig had foo foo amenities like that, so they had to go. Actually, I just like the smooth look, but I had to fill those holes too. Speaking of smooth, there were a few other spots where the body was nicely damaged from use and just blemished from the molding process, so I went ahead and filled those areas too. Here's a shot of the major body work done, right before I primed it:
After wet sanding and blocking the body work areas I had some minor touch up where the primer didn't fill. Incedentally, body filler has a tendency to shrink up a little bit as it dries. So, I spread a second coat of filler where it was needed, re-blocked, etc. Here it is, damn near ready for paint:
I shot an undercoat of primer to act as a sealer and to give me a uniform surface to paint over. I then wet sanded all the little nasties out of the sealer coat to give me a smooth surface. I shot a tack coat and two solid coats of color, sanding between each coat to keep mah shizz clean, know what I mean?

I cleaned up the top color coat and then shot three coates of clear to give me some room to work with when I cut and buff this dude. All in all, it came out pretty clean, but there's always some crud to clean up in the top coat. Here's the finished product:
Coming additions are REAL bumpers, possibly some rock guard paint for a two tone, some fender flares maybe, and some other stuff I haven't quite settled on. Anyway, more progress reports as they happen. Thanks for checking it out.
