Title: Exterior Screw Finish for Brake Cooling Scoops
Post by: Kiwishelby on February 23, 2023, 03:24:32 AM
Hi, my 70 Shelby has had one repaint since new, currently the two securing screws for the side body air scoops are painted, should these have a natural finish or painted..?

You can see a couple of original examples in the thread below Sorry for the poor angle but these were already posted and handy

+1  painted, but the paint didn't hold up very well in a lot of cases, :)

Those look like the screws on the '68s. They don't rust, are black and are Philips #2 heads.
I think that they are black stainless steel material?

The screws were plated a silver zinc or cadmium. They were unprimed and so the paint used to cover them up many times quickly flacked off . And since you recently had your car painted, the same goes for the carriage bolt heads under the front valance on ether side .

Also, since the scoops were painted off the car the screws were probably touched up after they were installed. Maybe with a small brush?  Anyone have anything on this?

The painting with a touch up brush is the most logical explanation and is the general conscience today. The same goes for the carriage head bolts holding the front valance.  I would be interested if anyone else had a different explanation.
