I don't know if there is a silver paint without metallic. Maybe a light grey will suffice, esp. if you're looking to flatten it. A good body and paint supply store should be able to help you with the paint and flattening agent.
Thanks for your help. I am trying to match the polished aluminum finish that you might see on the outside edge of a two color aluminum wheel. I'm repairing "curb rash." I mask the interior color and paint the outside edge. I'm able to match the color pretty well. The only thing that gives away my repair is the "sparkle" of the metal flake in the paint. I am using a single stage, but I could use a base coat/clear coat, as well. However, it seems that the clear coat high lights the "sparkle" and makes it more prominent. That's why I've been using a single stage paint. I'm open to any suggestions.
I thought you might be doing something like that. You may want to check out Alsa Corp. They have some of those type paints where there is an extremely fine metallic in it.
I've used the Mirra Chrome before. I think they have one that resembles chrome and one that resembles alum.
It has to be applied properly or it does not look right.
