Use Plasti-kote silver frost code: FM 8140. Remember, a clear coat on top will help the color match better although standing alone it's still very accurate. I've had good luck with it. Perhaps the new coat might be a tad darker but within a few days I noticed the coat matches better. Maybe let the piece fade in the sun a few days after the initial drying.
By the way, it's easy to run the paint. My recommendation is to put on a very light tacky coat before putting on a fuller heavier coat five minutes later. Not necessary to coat the whole area on the first try. Also, shake the can often but remember to do it away from the paint area or you will get a lot of residue splatter from the nozzle.
Some other recommendations, when painting side skirts or bumpers, remember to wash the entire area and more. It takes quite a bit of area to get the touch-up to blend properly. Also, make sure you paint with no breeze in the air or in a garage. Otherwise the overspray goes everywhere.
If you are painting a grille, I'd hang it from a piece of wire.
When painting with a clear coat, there is nothing to it. Just put on a full heavy coat. But be careful, it can run too. Don't over do it.
