Thanks for the info everyone!
I made a contact sheet with about 10 cars all painted in Lemans Blue and one shot of my “purple” engine compartment and took it to the paint shop. The mixer agreed that something went terribly wrong. He mixed up another quart of paint only to find out it’s the same purple color. We’ve concluded that Dupont has the formula wrong. The mixer is going to research today (and call Dupont) and see what he can find out.
If anyone has successfully painted Lemans blue and has the exact formula or PPG number it would certainly help. We have both the AR348 paint code and the Dupont 37001 number (and the Ditzler 14637 number but they don't sell Ditzler).
