I use PB Wheel Sealant and LOVE it. I've got aluminum alloy wheels, but the jar says it's okay for chrome. I started using it because of my excessive brake dust. I cleaned them really well with PB Spray & Rinse Wheel Cleaner. I recommend diluting that a little - it's really strong. After that, I applied two coats of the sealant. That was almost two months ago, and I still just use my soap and water to clean them. As I said, I've got different material and live in Alabama - no winter/salt concern. Somebody else will probably have better experience, but I've really had good luck with the PB wheel products.
