I'll give them a shot, I've tried showing pictures for stains but they where never the same, I guess solid automotive colors are easier. Good luck on the Confederate Flag.
OK. I had a look back thru my notes on one of these I did a few years back. The closest i found to the off white gibson used was an Ivory that Jaguar & Aston martin use. Aparently its a fairly common colour with car restoration guys who do old 50's & 60's body work. I found it at a classic car show here completly by accident. I rekon you should have a look at some body shop paint charts, Check somewhere that does repairs & custom paint jobs.
I'll inquire about Aston Martin paint, thanks alot man i apprecaite it.
I found the particular color i think your talking about, ill head to an automotive place and see if they can hook me up with some spray bombs, doubtful though.
Here's a link to the color chart for future reference.
