How can it be hard to take care of, its no harder than anything else. As long as you take care of your rims, it will last long, and does not rust. Very good choice if you like to show your car... really catches ones eye at a car show.
Polish is a ***** to try to polish up, some will say you can make them shine with wax's and what not just like chrome, I have had both, and polish rims are so dull you just dont get the shine as you do with chrome rims.
i think your thinking about chrome exhaust tips..yes those will rust, but thats b/c of the exhuast passing throught them. The chrome doesnt have any problems with rusting in and of itself that ive found.
Chrome will rust. No one can say it wont. and for you falconbballer15 the road salt will do a #, so if you get Chrome then Keep your stocks for the winter. But if you keep the chrome clean it looks better, like green said, water soap and TLC will do it. no big deal. (btw green, tips rust most because only the outside of the tip is chromed and it has lots of water in the pipes all the time. also most tips are cheap. :| ) 8)
