They will use the current formulas that the paint companies have listed as replacements for the original lacquer paints. In some cases, they are nowhere close to the original. After my paint came in from the PPG supplier, the paint shop test-applied a patch so I could approve it, clear coat and all. The color was nowhere near the original Pontiac paint chip nor like other Meridian Turquoise cars I have seen. So my painter tinted it to the correct color.

In addition, base/clear will never look like lacquer. They have different characteristics. Both can be colorful and shiny, but lacquer has its color at the surface and base/clear has its color on the bottom, so it looks "deeper".
