Word, I use this on my JDM-Type's. Keeps them looking nice and shiny. If this doesn't help, I read about asiandood (Civic guy) using a buffer and some rubbing compound I think. Might want to PM him.

 

There is glass cleaner that uses a buffer and it has a semi abrasive pad with cleaner. However I wouldn't recommend it for plastic. I have this glass cleaner. Its available at www.properautocare.com :thumbup:

 

if your headlamps are plastic like the JDM headlamps...use 1500-2000 grit sandpaper and wetsand to blur. take some 3M rubbing compound, or some plastic polish to buff it out. comes out looking like new. my headlamps and corners were yellow and dirty beforehand.

here's a pix of mine after the polish.




the headlights and corners came out like brand new. this method is only for plastic headlamps...not glass.

 

asianhood hit it right on the spot, i did the same thing and it came out like NEW *bling bling*

 

yup...
