English Custom Polish makes the best metal polishes. Get the Hot Environment and Chrome or listed as Hot Chrome. Its made specifically so it can work in areas were it gets hot. I use it on my wheels and my exhaust. Ive tried just about everything you can get in autozone or pepboys nothing compares to this stuff.
Hell no on the steel wool, it will scratch!
