yes and no.... mine were realllly chewed up from never ever being polished... oil redue caked on, really oxidiesd... i used a medium wire wheel to get the crud off , than polished by hand using 0000 steel wool and mothers polish... dont wipe the polish residue off from the steel wool and polish... wait 2-3 min than take a clean piece of steel and go to town on it tell all the haze from the polish is gone.... ( if have amothers poweer ball or power cone use it now with polish) if not take polish on a rag and rub and rub ... than take aclean rag and rub/polish/ buff by hand tell you have aalmost mirror finish
btw i just leanred the taken the clean steel wool after the steel wool and polish part today.. made mild steel exhaust pipe look like polished stainless.. so your shine should turn out even nicer than mine did in the pics
