My new donohue

Paint if if you wanna paint it. It's now your bike, and the original paint would have been chosen by somebody (a customer, most likely) who thought it looked good.
I think it looks fucking gash, fwiw - reminds me of a particularly nasty Trek paint scheme from ~15 years ago.
Just make sure you put the maker's name back on when the paint's dry.

Do what you want but also what I say. . .
