I stored this note ages ago, possibly from Mcromo - don't know if it helps:
Hornet side cover paint
Dupli-Color Truck, Van & SUV
For all the Canuks out there..
For what ever reason, Duplicolor does not carry in aerosol the T408 color in Canada
You can get the same color in touch up bottle with the brush - The color is GM 382E Pewter, and Duplicolor part# NGGM490
If you can find a local paint shop that make custom aerosol paints, you could give them the GM color code and bob is your uncle…
What I found to be the closest of all is Duplicolor's Stainless Steel, part number SS100. The color matches more closely than anything else I tried. It is just about as spot on as it's going to get- not too gold... not too silver... just right. The finish also more closely matches anything else I tried. It is also just about as spot on as it's going to get- not too shiny... not too flat... just a nice satin... just right. The metal flake is just about as spot on as it's going to get as well- not too flaky, sparkly, or glittery... not too plain... just right.
