Yeah the twilight Turquoise is a Canadian color, it is the original color under a horrible green-blue paint job on my project. No idea why it was ever repainted, there was a lot of Bondo on the passenger rear door maybe part of a repair + makeover way back when.
I've had the car almost 30 years (YIKES), and I am sure the guy I bought it from had never had it fixed or painted, so it's a really old repair.
I will be putting the original color back on, jury is still out on a white roof. I think the white (India Ivory) on the roof breaks it up nicely, but car was originally all one color.
Have done fire wall and started door posts using rattle cans I had mixed up locally, few pictures attached of how the new paint looks.
Have a great weekend.
