Negative, negative, even if old paint is atrocious and new paint is Joe Bell luscious. I do present this as information for those whom the financialization of old bikes is paramount. For others, like me, fretting over a couple of hundred dollars, which is one or two dinners out here in Our Nation's Capital, is a dissertation over angels dancing on a pinhead. If the bike needs to be repainted, by your lights/opinion, get it repainted, If it doesn't, don't repaint. If a repaint of a classic bicycle is a major financial decision for you, one way or the other, probably you shouldn't be messing around with old bikes that may or may not need repainted.

But again, just to be clear, you will never receive 100 cents on the dollar on a repaint job, it will always be a loss. Otherwise, all of us dumb clucks would just go around buying old frames, getting them repainted, and after enough iterations, we would join Warren Buffett's country club.
