Shaun my experience with these is that once they get rusty, old, discolored, etc. they are not worth replating. You spend alot of money doing it and the tubes may not be thick enough at the bends to take it after polishing for rechrome. And they never do look like they did when they were new (because they're still not new). I'd sell em on ebay or the swap meet and get a new set if you want them cherry.
Another option might be jet hot coating or similar, rather than chrome.
