These units are fully disassembled and cleaned down to the tiniest crevice using an ultrasonic cleanser with corrosion inhibiting agents. The existing paint is then removed chemically without using any abrasives and without damaging the underlying cast iron metal. A new base coat of paint is applied and tested for proper adhesion whereafter multiple coats of paint are applied over the base coat. The whole unit is then furnace baked to chemically adhere the paint to the cast iron for the best protection. The unit is rebuilt using all new wearable parts. New replacement parts include new Bosch shims, washers, clips, o-ring, etc. Checked to be in spec with a multiple recently restored and calibrated Sun distributor testing machine. Bosch dust cap only comes with product when you select Bosch cap and rotor.
