Does anyone know the correct finish used on the door latch striker? I need to do something other than paint (since it's obvious it gets scraped off from metal-to-metal contact). I'm sure they were plated, but other than re-plating, is there anything else that can be done (regarding re-finishing) that will resist this kind of wear? I've attached photos of my striker, and some photos of others that are offered for sale. The ones on my car have a head that uses a hex key, but I see that there are others with a head that use a star wrench. Which is correct for an E-Body? Thanks.
