zinc phosphate on rally center caps?

I've got a can of the zinc paint from 10+ years ago. It has a blue tint to it but looks nothing like clear zinc. It also doesn't have any texture to it. Maybe it has been redesigned since I bought the can.

Personally, I'd look at Totally Auto. They have textured argent in spray cans. It's not a perfect match to the original finish but it is close enough for a nice driver. If you need a better match, you'll have to get it from Rodger Gibson Restorations and it isn't cheap. Totally Auto might also have a Rallye wheel paint.
