Powder Coating sounds most likely AAACV8. The Sting Red paint on '66 is actually slightly different because the spray painter dude added more of some color in the mix (Orange?) and he has a Sting Red Commodore and so does the Auto Sparky guy I know, and both those Holdens beside my car look a different shade. I'm chuffed because it makes my paint colour unique, and a "one of" 😎 (cop that Muz ha ha) My Mechanic mate in Bundaberg is also Colour Blind and bought a HQ Monaro, he didn't know until he had owned the car for a month that it was PINK! Same colour as the one in the photo below, but it might be one of the colours you perceive to be Grey ? I'm sure your choices will look great on the 'Q' (it will sound great too !) I'm still going to lunch, emails kept coming in, not that I'm popular, I just have friends. You'll need a break from my 'waffling' anyway!
