Color-matching candy paint is fiendishly difficult, at its easiest...small touch-up of a relatively new paint job, using modern paint (3-stage) and from the same can. Some colors are a lot less cooperative than others. When it comes to colors with green pigment, assume that they'll run through the hallway, screaming, with scissors
. 47-year-old lacquer adds layers of complication. The OEM lacquer was 2-stage and the green pigment used in that era incredibly fade-prone. That's why most CBG bikes look more like lighter versions of CSB. The green lasted about as long as a campaign promise...after the election(!). You'd have to blend a color that, by definition, cannot be blended and, the application has nearly as much to do with the final color value as the midcoat formulation. It'd be a nightmare job for a seasoned airbrush artist.
I get what you're saying, it's a heartbreaker. That said, if you think it looks bad now, try doing a touch-up. Trust me on this one..."
you ain't seen nuthin'" until you've seen the results of a bad spot repair, of a candy color. Does the phrase
"I could've had a V-8"!!!!!!!! bring anything to mind?
