Doing the "big stuff" like air cleaners, alternators, manifolds, et cetera is where the fun is at because you get such instant gratification seeing big parts rejuvenated, Unforetunately, about 70% of the work is the small parts like bolts, washers, spacers...All of them get media blasted, wire wheeled on the pedestal grinder, and shot with clear satin. After that they are bagged, tagged and zip tied to the appropriate part or the best alternative. These are from the back of the AC compressor.
