Well . . . I fully understand the desire to use a single-stage acrylic enamel rather than the newer BC/CC system. It's about "the shine"! That hard shine which only the OEM-style acrylic enamel can produce AND what the DuPont Centari paint was all about. Hardener, when it came out later, made it better, by observation.
As for changing paint systems, that used to happen ever so many years. Nothing "static" about that market! Always something new and exciting, it seems, plus gov't regulations on VOC and such.
From what I found tonight, DuPont automotive refinishing paints are now branded "Axalta"? I was in a body shop a few years ago. The owner was an older guy and I asked him about what he was using. He replied that for the older cars, he'd use acrylic enamel rather than the newer BC/CC paints. "They look better to me", he said. I mentioned the old Centari paint and he said that the paint he was using (possibly Axalta, as I hadn't heard of that brand) reminded him a lot of the old Centari.
One place to shop for factory colors is the
www.autocolorlibrary.com website, which is aligned with the
www.TCPGlobal.com website. This should be a page with different eras of paint, by model year. Follow the drop down menus and you'll eventually get a page with prices and suggested products. From there, contact your local suppliers and see if they can supply what you need.
The issue with the older paints is the tint stocks and such not being available, OR the cross-over into the newer paint systems to yield the desired "Old" color. Each paint system seems to have its own unique tints and bases, which seem to not be direct crosses to the older systems.
ONE nod to using the newer BC/CC system is that that's what most painters are used to using . . . unless you can find somebody that knows how and has the equipment to shoot the single-stage acrylic enamel paints. The whole reason for using BC/CC paints, initially, was to use less actual color on the car, then use the CC upper coats for protection of the color coat Whereas the single-stage system is all color.
Some might differ, but I like to see the acrylic enamel paints where they were originally used. Things just "look right" to me. Others, used to looking at the newer BC/CC systems, use that as their "standard". To each their own.
