Your grill looks great!! Real nice work!

Not to hijack your thread, but throwing in my .02 here for another option.
I use Krylon "Dull Aluminum" a lot on my GM resto's.. It works well on grills, rally wheels, etc., and is the closest thing I've found without buying the correct but super-expensive "Argent Silver". I hardly ever see it in stores, but I keep a case here directly from Krylon at about $3.15 a can. For the grills and some of the other stuff, you'll need to follow with a clear coat as well.
