I'm doing a 66 GT 350 clone and need some info on Sapphire Blue. I have looked all over the internet and found the PPG color code to be 13075. My friend whos painting the car ran that number in his PPG computer and it dosent come up. He called his PPG rep and he said the number is no good and cross referenced it to 12832 which is Guardsman blue. I need a good PPG or Sherwin-Williams # for Sapphire Blue......
