I would take them to a rim restoration shop and have them looked at. It will cost you between $95 and $120 each for a total restoration, remount and rebalance but they will look new. Generally they will even change the wheel color if you like. I had mine powdercoated from light gray to matte black and they took out all the crub rash from the previous owner. Cant tell they didn't come that way. I dont think you will get that pitting out, the clear on those wheels are usually powdercoat.
