We wanted the underside of Track Rat to look as clean and well thought out as the side that sees daylight. It’s not complicated to do, but it is messy and time consuming. Thankfully, the body was on a rotisserie since performing this work in the inverted position is a literal pain in the neck.
Fortunately, the floors of our Camaro were in great shape—no rust or big dents—but there was a ton of built-up grease and grime. The best way to get rid of it was to use a scraper followed by some Scotch Brite pads and lacquer thinner to get down to clean metal. Had it been worse, we would have moved up to a wire wheel and some power tools.
Once everything was suitably clean, we broke out our Lord Fusor gun and seam-sealed all the cracks and crevices. While not absolutely necessary, it’ll add to the overall fit and finish of the car.
We’ve had great luck with the Wurth line of products, and their Stoneguard is no exception. It will accomplish several things: one, it will rust-proof the underside of our Camaro, two, it will fill in any crevices that didn’t get hit with the Fusor seam sealer,and three, it will help protect the metal from stone damage. It’s sold in Aerosol spray cans, but for large jobs, this 30-ounce bottle is a better idea.
The process is pretty simple. We loaded a can of the Wurth SKS Stoneguard into the multi sprayer and started laying it down. The 30-ounce cans run about $50 each and we went through three of them coating the bottom of the Camaro and inside the front fenders.
After a couple of hours the Wurth dried and turned a nice low-gloss shade of black. Total time to clean, prep, and shoot the underside of the Camaro was about eight hours.
