Because of the really crappy weather we've been having here in the east and after a harsh winter my comptech exhaust have lost their shine. They have tons of road crap on it and it doesn't look very good upclose. A friend suggested I use #000 steel wool pads to clean them. Well, it really works. It restored the shine and they are nice and smooth again. I just did the tips to test so once it stops raining, if ever, I'll do the entire exhaust. You can pick them up at home depot, or any hardware store I believe.

 

i just use wax works fine

 

I use Nevr Dull

 

I used Mothers Metal Polish....mine are as smooth as a babies bottom

 

dont' use metal / steel wool, it's too abrasive... Eagle one had an aluminum polish and that's work great too... not never dull, it's the one that it never hurts aluminum wheels and chrome, it's like a dry wax and you apply it....

but I would first spray some WD40 to pre clean the exhaust first, then apply those polish

 

I've been using Flitz or Simi-chrome.

 

I used Autosol metal polish and it works fine too.
