Retaining Ring
Designed to hold the large light in place, they are pretty well abused. Dirty, painted, and rusted. The paint was chipped off, the dirt scrubbed off, the rust brushed off. The entire piece was polished, and the rust areas were resprayed with silver paint in loo of re-chroming or replacement. I taped off the area to be sprayed on this one, though after the fact I prefer the free spray and polishing off the excess than taping off the area...
Adjuster Before and After
The primary function of this piece is to be able to adjust where the lights are pointing. Cleaning this piece left most unsatisfying results. The rusted area was pitted and generally abused by the fact that there was no dust ring seal to keep water from accumulating on it. The paint was chipped off as usual. The rusted area was treated with several rounds of brushing, vinegar, rinse and repeat. This one was in worse condition than the first.
After cleaning, I spray-painted the adjuster with the lovely silver paint. It looks simply fabulous, I even pooled the excess spray in the rusted out areas and ended up with a smooth finish. Then I placed it down on slightly sticky paint and messed the finish on the bottom. It's not seen and will not mess with the protection provided by the paint.
