I can suggest 2 places.
One is obviously a GM dealer, preferably an ex-saturn or pontiac dealer..
The other is Langka, here is their webpage.. LANGKA Paint Chip and Scratch Repair
In either case I would recommend that you have your paint code handy, which is inside your glove box on a sticker for your color, with langka for sure you will need it, expect to pay at least $20 and up for a small bottle, gm's includes a brush (which sucks to use, some lately also include a needle, like a pen) both work lousy BTW, AND you will never get it to look like original sorry to say....
WA9260 is what I have for CP red.., but I believe you need the 3 letter code..
which in your case I believe it is 74U, please confirm that from inside your glove box.. look for those 3 letter codes to confirm..:cheers:
I used Dr. Colorchip also. AMAZING stuff if you take your time and do a couple coats on worse chips. I fixed 19 chips total and I defy anyone to find them -- it took me a long time, but it is flawless.
