Funny but observe 'how the preserve at all cost' individuals, certainly admired repaints and vote as some of the best at the bigger classic bikes events/ CR Cirque, etc.. They'll even overlook the beautiful repaint, yet critique the brake cables routing under the handlebars or the tires labeling is incorrectly positioned upon mounting.
Examples include the work and art by Joe Bell, Jim Cunningham to even the late Brian Baylis.
Its all in ones state of mind including market value influence.
If you like a tattered rusty chipped and scratched paint on a classic, because the market value says its worth more and believe its only original once, then have at it.
