It is to some degree more efficient, at the stripping and repair end, and of course in the clear coating. When it comes to the tinted lacquer application it varies between makes, models, and years. If you are doing all 1937-39 Philco cabinets they are all pretty similar, throw in something like a Grunow or a 1930 era Sparton Equasonne then it gets more tricky. You don't want all of your sets looking like Foggy the shill seller on fleabay where every set gets the K-Mart guitar finish.
