My new set of used OEM wheels have nasty corrosion on the inside of the wheel. Is there any easy way to remove it? I have used a wire brush and a drill to clean away the really superficial stuff, but some seems really deep. I dont want to sand/go deep for the sake of wheel integrity and balance. How do I clean the corrosion like that?

or would i be ok to just clean them and spray sandable primer + clear coats over them? would the corrosion still wear under the layer of paint?

My goal is to remove it if possible and prevent it from forming after I install these wheels.
