69 Barracuda grille shells

Getting close to doing the resto on the plastic shells and need to do some mending first. Question is what would be best to refinish them. I was thinking argent silver. Any suggestions?

I've had good luck using spray bombs including a few high heat paints and matching them to a known good color. It may cost a few cans I won't use because they were off a bit, but some are so close its amazing.

These days I find the highest quality spray bomb paints at O'Riely's or Autozone.
