try paintscratch.com
they are a lil pricey in general, but have excellent stuff.. Ive ordered '01 DWP from them a few times in spray cans.. they gave me a can each of primer, base white, pearl white, and clear.. for touch up and also to paint my eyelids, etc.. the key to matching this type of 3-stage is how much of the pearl u put on, so i just did one coat at a time until it matched
i think they also sell it in quart cans, etc now too
matches real well..
hope that helps!
