What is the best product to use for sealing polished wheels. I should be getting my Smoothie II's here in the next week and dont know what to use to seal them. I thought of Zoop Seal but I dont know about paying over $100 for something that might not last that long. Plus once the Zoop Seal is on you cant use any cleaning products on the wheels because it will take off the Zoop Seal. I obviously dont want my wheels getting the oxidation look to them. Anybody have any tricks up their sleeves??
