Might be worth giving Orange a shout. I’m sure I’ve seen them do a polished full suss frame of some description.
Stripping the paint and polishing it isn’t too bad to do, although time consuming. I’d definitely recommend lacquring though as it’s a pain to keep shiny otherwise.
My local powdercoaters have just started doing aqua-beading, which removes paint but doesn’t leave marks on the metal like media blasting does. Might be worth looking in to. Will try and find their number for you.
