If you're set on doing it yourself, Busch Enterprises out of Charlotte NC (704 588-2067 is the last # I had) makes a product #64016, Clear Coat Remover, to strip the CC off a wheel.
You'll need to remove the wheels from the vehicle (and the tire off would be even better), paint the product on with a brush, let set, then hose off. Wear old clothes, eye protection, rubber gloves blah blah blah since it's harsh stuff.
Then repolish and recoat if desired.
Or, take bretfraz's suggestion and find a place to do it for you.
