In addition to promoting a friendly competition between the two titles, the Build-Off staged between Custom Classic Trucks and Classic Trucks has served as a platform to present a variety of tech features to our valued readers that contain information applicable to not only the '67-72 series of F-100 Fords, but to all trucks as well.

In keeping with this theme, the following story on creating a Gasser-style appearance for our '72 F-100's interior demonstrates how to properly prepare the surface before applying a heat barrier. And by virtue of leaving Lizard Skin as the only sound deadener/heat barrier in the '72's cab, we will be able to accurately evaluate its effectiveness.

The first step after gutting the interior, removing the seat and floor coverings, and pulling the gas tank out is to flush out years of accumulated hard-packed dirt and gobs of loose dust by filling up a 5-gallon bucket with hot water mixed with Tide and going to town with a sponge. Not wanting to leave water trapped in any of the numerous places it could collect and cause future rusting problems, we used compressed air to force-dry the cab's interior.

Next on the agenda is to screw a coarse wire wheel onto our trusty 75-model Makita polisher/grinder and knock off as much rust scale as possible. The key to stopping rust is proper surface preparation. In addition to the coarse wire wheel, we uses a 40-grit grinding disc plus some 40-grit dry sandpaper to reach in by hand to the areas where the Makita couldn't stuff its snout.

The next wave of organic-based liquids used to purify the '72's cab is a 1.5 to 1 mixture of KBS Coatings' Aqua Klean, which far exceeds Tide's capabilities to strip oil and remove contaminants from the metal's surface. After this, it is time again for the air hose.

Well, wouldn't you know it, just like on the build-offs on TV, after getting the cab floor down to the real nitty gritty, I discovered there was a lot more rust damage to the sheetmetal than first appeared. Unfortunately, unlike some of the reality shows on TV, we don't have any little elves to come in at night and catch us up for the next day. This issue is sitting right on the deadline, but I'm not about to cut it short and Mickey-Mouse the truck with as much effort as I've already put into it. So I'll finish this tech based on my knowledge from using KBS Coatings and Lizard Skin in the past. At this point, I got stopped in my tracks, but the good news is there is a welding supply store near me that sells Miller products, so after I turn this story in, I can fire up my new Miller Spectrum 375 Xtreme plasma cutter, blow out the rusted bits, and weld in some spot patches with my new Millermatic 252 MIG welder. In the meantime, I'll keep pushing for the November deadline Grant and I are both facing to meet at the Scottsdale Goodguys show for the Build-Off's finale.
