The short answer is "NO". The clearest shellac still has a slight amber color. Even after it dries, it can be dissolved with alcohol, and it is prone to water spots. It is also softer than lacquers or enamel, so scratches easier. Shellac is a resin dissolved in alcohol. Unlike many paints, it does not "cure" (change its chemical structure) as it dries. It is an excellent finish for furniture and musical instruments, because it can be easily repaired, but I would not use it on a model car.
