I got a Nishijin B dolphin one, and most of the paint on the center, as well as the small bits have peeled or cracked.

I searched around and finally found another (most seem to be dancing dolphins) on the site:

Which probably has not been restored, but there seems to be a huge, flat concentration of blues... while I love blue, it makes the features less distinct when they are all kinda close?

My question is that if you say, add some metallics and change the colors a small bit, is this going to wreck the machine, completely ruin value etc? The machine is otherwise in good shape.

Oh and how in the world to clean the clear tube, this one is one piece!
