Thx guys. I didn't find anything on the net so I figured this would be the best place to ask.
Thinking of just doing the pin in black seeing as it’s almost covered by the rubber.
Happen to be working on all my windows and glass so can share some photos. These vent wing parts have been removed for cleaning/polishing.plating. One of these pivots was good but the other was rusted. So one of these buffed on my wire wheel and clear coated. Can you tell which one? If you look really, really close you can.
Stainless comes in at least seven grades. Their rust avoidance comes not from it's "purity" but from the addition of other metals. Hence the different grades.
