The bumper mechs were stripped and cleaned and rebuilt ready to go back onto the pf when the time came. One of the diodes on the coils was cracked so all three were replaced.

All of the screws and posts, wire guides etc went thru the tumbler, 2nd pic shows the parts after they came out of the tumbler. The metal bumper brackets were tumble polished as well.

The stainless guides in the 3rd pic looked to  have been polished and not grained so i gave them a light wet sand with 800 grit wet/dry and Windex then polished them with Autosol.
