this is tough one..... is riding it the way it is going to bug you? then repaint,

but then the question is: good quality auto paint job or good quality powder coat .....I.e how much are you willing to put in to it, cost wise. also in question is what local resources you have.

note I did not include DIY rattle can, as the result can be stunning, but the durability sucks.....this could be an option if you can DIY with auto paint, but a proper paint job is a lot of work (strip frame 100% of old paint, acid etch primer, sandable primer, sanding, multiple color coats within recoat times, multiple clear coats)

personally, I like how it looks for a reason I can't quantify, it just looks cool. and has bonus of be a bit of camouflage to the bikes value as you sit drinking coffee at your local cafe
