This is a bit of a tangent, but I recently went to a Napa parts store which has a big automotive paint department and asked them to mix a small quantity of Granada red ( BMW 023 ) paint to use for engine bay touch up. The guy searched thru his computer systems for what seemed like a long time and finally said he could not find a recipe for that color. I showed him a can I had mixed at that store based on the color code 10 years ago. He said it looks like it has been deleted from the computer systems he has access to. He would need to custom blend the color by matching a painted part from the car. He had data for other BMW red colors like Verona ,of similar age, but not Granada.
Anybody know what is going on here? Do paint codes get deleted after they get old?
