[STL240SX]

Anybody know the paint color code for the light metallic silver? Sorry i dont have pics, but most of you probably know what im talking about. Also , how much does it cost to buy this paint? Sold by gallon, or what?

I think I know the color you are talking about, my friend has it on his '90 fastback, if you go here: http://socal240sx.org/faq/colorchart.html It says its Platinum Blue Metallic, color code KG1
