Guys,
I have no problem finding argent silver. My local Home Depot, Lowe's and Wal-Marts have plenty...in different brands, and shades of silver. Its the same situation with my Ford friends trying to find the closest 'Ford blue' engine paint. Also, a tip on some other hard to find color matches: use either Krylon (preferred) or Rustolum 'Bronze Metallic' for what is used for black metallic, with a touch of gold in it. Perfect match...from a rattle can.
