When I did the `70 GSX a few years ago the car had the original paint on it. I removed one of the sport mirrors, rubbed it out so it looked new and shipped it to Dupont for a match. The paint number they sent me for Chromabase is 5283 K, Alt. 1. It comes up Sunflower Yellow on the computer at the paint store but it was a perfect match to the original paint.
I agree with you about PPG, but where I work we use Speis Hecker. I cross referenced the DuPont code. I'll still have to see how it looks after I mix some up.
Here is my concern. Sunflower was a 71 Chev Color: http://www.tcpglobal.com/autocolorlibrary/aclchip.aspx?image=1971-chevrolet-pg01.jpg If you look at the Chevrolet paint code and refer to the bottom of the chart, it says it was also a spring 1970 color. So was Saturn yellow for Buick. But the PPG code for Sunflower = PPG 2338 = GM code 52 = http://www.labib.com/71corvette/ We have had many members successfully use the PPG mixing code for Saturn yellow in the link above (#81838) which is a different number. Plus the Sunflower yellow chip linked above does not look correct to me.o No: Another member in the link above, Stratoblue72, who has a paint and body shop, says the modern Dupont code = # 5139 while yet another respected member in post #6 above says Sunflower yellow = Dupont # 5283. Something is out of round here.
Ok ,so what you're telling me is that ppg # 81838 is a closer match to Saturn Yellow than the sunflower yellow.
I think it is a paint code that has been passed around on this Board for a long time and used by many. There is an issue here with the code numbers. We have the original lacquer Dupont code for 1970 Saturn yellow in the link above. If someone has the same lacquer code for 1971 Chevrolet Sunflower Yellow, we can compare the two. If they are not identical, then Sunflower and Saturn Yellow are different.
Don't know if this helps or not but I had my 72 painted yellow about 9 years back. Had no idea that Saturn yellow was an option in the day until I read you post today, but that is the color I figured I wanted. I think the paint was from around 1999 or 2000. The code on the can is 685H (could be C 8 5 H, but I think its the 685H). From what I can read on the can (that's not sprayed over) it is from Dupont.
DO NOT put a Chevy paint color on it, even by mistake. What do you want to do? Make your car slower and uglier?
