Well, this is super frustrating. Just got the wheels back from the powder coater. I gave them the PPG code found above. They weren't able to buy the PPG in quantity less than 55# and unbeknownst to me called their supplier and was told that Tagger brand RAL9010 was a match.

Anyway, they put 2 coats on, did a fantastic job, but the color is not a close match at all!!!! See photos below. The PC is obviously going to be more glossy than paint, but it is too bright and too white.
See attached photos. The rattle can I got of Wimbledon White off the shelf at Autozone was a very good match to the inside of my glove box and inside top of hardtop both of which obviously don't see the sun.
So, I can't see whether the "PPG Wimbleton White ceramic powder pct87210q" would be a good match, but can definitely say that RAL 9010 isn't.
I will now have them painted, and should the paint chip, will have a nice PC base layer that is only few shades off and will help hide the chips! If anyone knows if any special prep is needed to paint over PC, please respond here:
