trust me its very effective, i havent used any really fine grit sandpaper but ive waxed and buffed mine out with an electric buffer and there is a huge improvement.

 

sounds good, i'll have to give me headlights a try.

 

I've used "Brasso" on some old faded plastic lenses.

 

meguiars makes a polish especially for headlights and plastic housings

it comes in a little baggy and costs less than a buck. works nice. made my headlights look new and shiny

smells nice too

i got mine from autozone

 

I use Novus 1-2-3 good stuff

mainly use the cleaner and then the polisher.

high speed buffer may not be a good idea sine our head lights are made of palstic, high speed + friction = heat.. what happens when plastic and too much heat meet up?

best to use ur hand, lets u get in shape too!! LOL
