Aww, a repaint? I'm a huge fan of character in my typewriters, ie scratches, scuffs, and general imperfections that showcase the machine's history. By just looking at the paint on a machine you know if it was used, abused, or stored in perfect shape. Often there are patches repainted, even whole sections redone, and then you know it was used enough to have worn out a first coat but reliable enough to earn a new coat of paint. I understand touching up spots on moderate to near perfect machines, but I never tamper with the paint on my well used bangers.

However, if you really thing a repaint is the best option (White with gold trim would be stunning!) the KMG would not be a good candidate at all. As you said, much of the insides are connected directly to the body. You can't simply remove a few screws and be done, this would be a very large undertaking. However, leaving the panels on the typewriter while you paint them is an even worse idea. I have a KMM that was repainted a sandy tan without being disassembled, but was not adequately covered all around. There is tan paint everywhere it shouldn't be, even though much of it was protected.
