I'm in the middle of painting my 85 Iroc-Z and we're gonna go get the paint in a couple days. on my rpo sheet, it lists codes 30L and 30U, which are 30L : SECONDARY COLOR, EXTERIOR, GRAY BLUE MET (91) and 30U : PRIMARY COLOR, EXTERIOR, GRAY BLUE MET (91). when i go to get the paint, what should i tell them? Gray Blue Metallic or what? also on the rpo sheet, it says enamel - WA - L8587 and U8587. What are these for and what do these mean? Any help would be appreciated.

 

I believe the L8587 and U8587 mean Lower and Upper colors. Usually the paint store can take the year, make, model, and color code of your car, (30 in your case), and get the paint mixed the correct color.

 

When I got my car painted, I told them the WA number of the color I wanted and they new exactly what I wanted. When you go to get the paint you should tell them that number, in your case 8587. The "L" and "U" refer to upper and lower. Since IROCs are monotone, the numbers are the same.
