I personally never wax mine. I do however use RainX on them, along with the window. Usually 3-4 coats. Nothing will stick to either surface for awhile.

 

+1 thats what i do

 

ive waxed my headlights, taillights, and windows (not the windshield) and i havent had any problems so far

 

i been wanting to try that plastix from meguairs i have a few lil scratches on one of my headlights.

 

I wax everythign except the windsheild and rear window, then i go over the headlights and taillights and the mitsu diamonds with windex and the windows with rainx

 

don't use rainX on plastic, it eats it.
don't wax windows because it's not optically clear and won't really do much
don't wax any plastic - if you do and it doesn't look like crap then your wax sucks in general

plastix is good for any clear plastics.

 

My lights look like theyve been sand blasted-yellowish...will plastix help this?

 

you would want to use a plastic specific polish. wax doesnt polish anything, it only seals up.

in general, when you paint somthing you do this:
Paint
wet sand out the 'orange peel' and imperfecions
polish to a shine
wax to seal

too many people think that waxing is polishing...you can apply wax to your car anytime, but polishing your car is what makes the paint shine...

fwiw...

i havent used plastix, but have heard good things about it from others that used it to smooth out a bad Niteshade job.

 

Wax your headlights/taillights often to prevent oxidation.

Polish your headlights/taillights ONLY if they're oxidized. The reason I say this is because polishing actually is removing a small lair of plastic to make it smooth. If your lights aren't oxidized and you decide to polish them, you're removing a part of the protective lair.

This is what oxidized headlights look like: http://www.autodetailingsolutions.co...ightBefore.jpg.

 

yeah mine are starting to look like that but not that bad...I dont want them to be that bad!

I tried rubbing compound but that didnt work...what polishes plastic? i need to go to pepboys...

 

If you have a orbital polisher, it will make things easier. The general rule of thumb is to start off with the least aggressive polish (and polishing pad, if applicable), check the results, and if it needs something more aggressive, move up. If the oxidation is really bad, you might have to start moving into the fine grit sandpaper (1000+) with water (aka wet sanding).

 

I just toothpasted my drivers side headlight. Looks awesome, you'd really have to look to know it was foggy at all.

 

plastX works well

 

You should really buff them first then wax them. And yea don't use Rain-X on them but any wax is fine on them.
