I refinished the door latches. They were one part that didn't make it into the batch of parts I had plated years ago and they've bothered me ever since. It took a bit to get the finish right on them. I looked at many pictures of these online to see how shiny and how yellow they are originally. They seem to be shiny and only a little yellow on the early cars so I tried to match that. I'm not sure but newer cars may have not even been yellow zinc.
