I can't remember what the paint was on the bracket supporting the wiper motor when my 1958 TR3A was new, but it was black like the rest of the car. I don't remember any krinkle black on the support. In 1989 when I had the car totally paints (all pieces off the car0 during my restoration, the support was sprayed glossy black like the inner fenders as well as the outer fenders. No points were ever docked because it was glossy blsack at TRA or VTR judged concours events.
