New member here so apologies in advance if this has already been addressed; I did some searching and couldn't find any details. I have a summit white ZR2, which has the gloss black front and rear bumpers. I went to the dealership to purchase touch up paint for a few rock chips and it looks like GM was kind enough to leave it as an anomaly. Research on google leads to a thousand answers. For those of you that know, or have done this, what paint code for the gloss black should I use for the rock chips? And where did you purchase this?
