Plastic Polish from Plexus and Renovo are amazing for plastic http://secure.detailedimage.com/Merc...y_Code=Plastic. However for exterior side Rain-X is a nice touch too.

 

I second Plexus folllowed up with your favorite wax (I put nxt on mine)

 

all the products mentioned above are great and should work. Personally i use Klasse AIO (all in one). I've used plastic polishes but I noticed they would cause little scratch marks even if i used a microfiber. I love AIO because it contains no abrasives, but it is a chemical cleaner!

The chemicals in AIo dissove those nasty headlight marks, but is gentle so it cause no micro maring.

 

Rain X will keep rain off, but if you want to have the "raimbow look" on them then 3M Plastic Cleaner and Polish is what you want.

They are really hard to find and somewhat expensive, but they are worth it!

3M 39017 (plastic cleaner) 3M 39010 (plastic polish) <-- search for those on google and buy them, you wont regret it.

 

i had the hazy headlights and i went to autozone and bought the Meguires plastic polish, it was 99 cents and comes in a little packet.... works wonders, the headlights look better then new and the haze is all gone....

 

Hazing on the lenses is a known problem. There's no getting around it because of the ventilation in the housing. You can use Rain-X or whatever, but you're still going to need to clean it. 3M is the STUFF! and yeah, it is hard to find. Not too sure if Checker carries it.

Any guys in Hawaii reading this, I think NAPA is the only place that carries it.

 

Yeah 3M polish and cleaner are the best. Can't remember where I bought them, but I remember them being expensive. Just look up part numbers google "3m 39017" and surelly you'll find it.
