1995 Cobra R Paint Color

Hello all, I have one brand new 1995 Cobra R wheel and 3 old ones that need to be repainted to match. I've bought two different "argent" paints offered by VHT and Ford Motorsports, and neither of them is a good match for the original rim. The main difference is that the paint on the original rim is metallic, with lots of small shiny flecks in it, while the two cans of argent paint I've found so far are not metallic. Does anyone else have experience finding and using paint that matches these rims? I'd appreciate any help you can give.

Thanks, Aron
