Cleaning suggestions?

Bet she was good looking and blonde?

Well I had the same problem on my single wall Mufflers.

At least I took a shaver blade and cutted the thick stuff. Than polishing with chromepolish. But still left some scratches from the blade and some dark texture from the plastic.

Next time take a ugly one with brain for a ride

I see a lot of you wanted to know what she looked like. She is a cute little Russian brunette.
