If it were me, I would go to an automotive paint store (not a body shop) and get them to use their handheld paint color detector(I dont know the correct term for the tool) to match the color. It may not be exact, but itll be close. Get them to mix you up some, the smallest will probably be a half pint, but they may go smaller amounts. I recommend getting a really good hobby shop style brush, really fine tip. Obviously you could not use this method for huge chips as it will show up, but more than likely they are small. I have used this method on some of my wheels from the past and has worked very well, you dont want to make strokes with the brush however, just dab the chips/scratches with the brush with small amounts of paint. It has worked for me. Good luck!

 

I would call Advan or the retailer you bought them from and they'll usually sell bottles of touch up paint for 15-20 bucks

 

thanks!!!
