I am starting to get some rusting on my chrome and bolts. I noticed on my exhaust pipes it was a little like sandpaper. I buffed it out, it took a little elbow grease, but it buffed out nice. I am curious to know what others do to prevent or clean your metal. I also got a little chrome polish on my black engine fins, anything to clean that??. What is a good cleaner or polish to clean chrome and aluminum?..
