In this episode of the Trans Am project, Mark addresses the integrity of the front subframe by removing it from the body and stripping it down to bare metal. This requires cleaning and degreasing, followed by a combination of wire brushes, abrasive discs, and media blasting to remove all the old paint and rust. While it’s out of the car, he takes extra measures to clean up unsightly old welds and seams, remove factory weld spatter and knock down high spots. He protects all the work with 2K epoxy primer before giving the entire subframe two coats of gloss Chassis Black.
