Information I have is that there is only one source for reproduction grills at this time. Herbs has the Dark Argent in spray cans and I bought a couple cans. I did a little test spray yesterday and it is pretty close color wise. It has a lot of texture when it dries and a lot of the aluminum flake in it. The only visible fault I could find may be the flake size compared to an NOS part which is a bit larger. I think this is a good option and the price ($19) was right. I'm just going to mask off the repop grill and bezels and re-shoot them.
