Polishing AMG chrome exhaust tips

I want to polish up the quad chrome tips on my cl55k.

Anyone have any ideas on the best way to do this without scratching the chrome.

My Alpina was easy as it was stainless steel, i just got some really fine sand paper and sanded the hell out of it till it was shinney again :lol:

However i doubt i can do this on the AMG.

Any suggestions?

I've read vinger is meant to work.
