Yep, a bit of wire wool works a treat when it's quite bad. Need to do mine properly again as theres some strange marks appeared that I need to get rid of!The exhaust tip on my car went very dull and had brown spots all over it. No amount of Autosol and buffing would get it totally totally clean.
I got the Autosol again and some 0000 grade wire wool from eBay. Totally soft and didnt scratch up my tailpipe (which for those that know me is precious to me! lol)
It was SO much easier and quicker than buffing and buffing and buffing away and I was very happy with the results.
I don't mean to hi-jack but underneath there are two screws (can't remember their type) but just unscrew them and pull them off. You may need another two screws as they're a screw but have a sort of casing around them (i'm not the most technical) then just pull the rear valance off. Hope this helpsHey Pink - realised it would be a lot easier to polish the tip of my milltek if I removed the plastic trim as you have.
Can you describe how you get that bit off (and on again afterwards?) please.
