the driverside was by far the worst, but i did both anyways. here is a before/after pic. it is way way better than it was. but up close you can still see some haziness that wont go away. but oh well.


btw, i just used 2000/2500 sandpaper and meguiars plastic polish.





and after...

Use a larger grit. Use something like 800 to 1000 first. Then go to a 1500 and 2k then polish. It will get deeper into the plastic and polish better.

^^^^ i agree. i used 1000, 1500, 2000 and some polish and they look brand new. looks better for sure

x3, use a 1000grit then progress up. u started with a very fine grit. i ending my sanding with a 2000grit.

1st timer

when you use 1000 go side ways and when you switch to 1500 go upwards and the next sideways and so on,this way the 1500 will remove the 1000 scratches and the 2000 will remove 1500 scratches and the you can polish.
When you move on to the next grit look at your headlights from an angle up close to make sure all the previous scratches are gone,Take this from a machinist that also polished plastic injection molds for 10 years

i went all the way down to 600, but i dunno if that is what left scratches :P go 800 1000, something between 1000 and 2000, then 2000. i took about 30-45 minutes on each headlight xD

haha that sounds like overkill to me. i started with 1000, 1500, anded with 2000.

my first time, i started with 2000 too, and it wasnt working. dont be afraid to really get in there, use some elbow grease and a lower grit, follow the advice from 1st timer, thats good and proper sanding technique.

Like some have said, start with a larger grit and apply more elbow grease!

I would never bring anything less than 2000 grit close to the lenses, might as well use steel wool and ruin the headlights once and for all.

Problem with using anything less than 2000 grit is that you can never get the deep scratches left by those sand papers out.

Here is the process I use to take out the yellow in the lenses and rejuvenate the lenses, after I am done the lenses are at 9/10, where 10/10 would be a set of lenses on headlights that are right out of the box.

-- Soak a 4"x4" piece of 2000 grit sand paper in hot water for 10 mins.
-- Take the wet sand paper and rub it against a hard surface for a few seconds to take away the initial abrasive surface off of the sand paper.
-- At this point the sand paper should be as smooth as dry paper.
-- Throw some soapy water on the lenses and work on the lenses, go side to side and then up and down, do this till you dont feel the stone pits in the lens and also till you have taken out the yellowed clear coat from the lenses.
-- At this point wash the lenses, sanding the lenses should take 5 to 10 mins.

Polishing.

-- Depending on how bad the lenses are I use a few different combination of polishes.
-- You would need a rotary buffer, elbow grease just wouldnt do at this point.
-- First you will need the buffing heads, I dont have the name of the kit but you can pick it up at napa, it comes with 5 presoaked sponges and drill adapter, you will use the drill adapter and the sponges along with the following polishes.

-- 1st polish

Novus marine grade plastic polish

ebay has the kit that you can buy with all three polishes



-- Use the soapy water to soak the lens, start with polish number 3 and spend close to 10 mins on one lens, repeat with polish 2 and then clean with cleaner 1.
-- Then use mcguires plastx, you can get it from your local napa/autozone



-- Make sure that with each polish the lens is lubricated with soapy water.

Depending on how bad the lenses are it can take you anywhere from 45 mins to an hour to do one lens, may be even more .

JnC, you're saying to polish while the lens is wet with soap water?
