refinishing rims has nothing much to do with auto bodyshop la, any shop u sent to, they will send it out to Panther's, Green's etc...
the most important part is if your tire's sidewall is damaged, might as well get a new one (depends on the tire's life, might recommend at least a pair) as well as alignment afterwards...
refinish is not "necessary" as long as the wheel is not warped or chipped or leaking air, if it's cosmestic damage, it depends on how perfect you want your car to be
i work at a shop and usually to fix a rim it start with $175 just the rims i think this maybe the pirce you got but also depence on the size of it and stuff
