just did mine, the dupont number is: dupont centari 44146A
i got mine from ace fogdall in cedar falls iowa.
about 20 bucks a can, perfect match.
they also have regular silver and plasticote in rattle cans.
might save a few bucks if you buy a pint from an auto body supply shop and spray it on yourself if you have the equipment.
although i could have used my binks gun, i didn't because i just needed to touch up a couple of places.
the rattle can was fine, one was just enough to do the tounge and tool box.
