The cost of refinishing stock hardware can be very expensive so I decided to refinish my own at home. The following pictures show the refinishing of some phosphate and oiled parts. In this case they are the rack and pinion mounting bolts.

This is the refinishing set up, Phosphoric acid solution, water bath, denatured alcohol bath, and the oil bath.

The bolts as removed from the car before cleaning.

The bolts after sand blasting and wire wheel brushing.

If anyone is interested in the process you can PM and I will forward you a link to explain the process in detail.
