So i did this today and let me say, it was quite the adventure. First of all the original post says this job is going to take you an hour a light at most, BS!!!!

It took me 2 hours a light, i wasnt messing around with something as important as headlights. Doing this really intimidated me because I was worried that id do a poor job and id regret it, but in the end it turned out way better then i expected.

What you will need!

-small plastic container and a tap for water
-320 grit sandpaper (or a little higher 400/500 however your asking for the first step to take longer)
-800 grit sandpaper
-1500 grit sandpaper
-2000 grit sandpaper
-Rubbing compound and a shammy dealio to put it on
-a nice rag to do a bit of hand buffing
-Some form of polishing pad with machine function (I used my handy black&decker mouse sander with a polish pad)
-Plastic Polish (I used meguiars clear plastic polish, an older version i think in a light blue bottle with no fancy graphics, i got it from car quest auto parts)
http://www.meguiars.com/estore/product_list.cfm?sectionname=Consumer%20(Meguiar%27s%20Brand)%3EClear%20Plastic%20Care&sectionID=15101 (http://www.meguiars.com/estore/product_list.cfm?sectionname=Consumer%20%28Meguiar%27s%20Brand%29%3EClear%20Plastic%20Care&sectionID=15101)
-A Buffer top for your drill or grinder wheel
-arms with stamina for 3 1/2 hours of sanding

Here is what my lights looked like before the whole process. EWWWWW

step 1
-Tape around the light casing, protect your paint people cause you will bump into it trying to sand the edges so tape around the lights to make sure your bumper/quarter panel doesnt get scratched
-clean the lights of bugs etc etc

Step 2
-Begin sanding with 320 grit sandpaper Vertically (it works out better then starting Horizontally because sanding with the 800 is a lot more work so at least sand the longways on the harder part to make it a bit easier)
-Make sure to pay special attention to the closest corner to the grill and along the edges, as you will tend to try buff the middle rather then put in the hard work of buffing along the corners and edges.
-Sand it up really good with the 320 trying to get a consistant coat of scratchyness across the entire light. Dont be afraid to throw down a fair amount of pressure and speed on the thing to make sure its getting the Pits out
When your done sanding with the 300 it should look something like this
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/320grit.jpg

-now take a wet rag and wipe the dust off and it will look something like this
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/wipeitoff320.jpg

-Get tuneski's your gonna need emNow heres where some wierd shit happened, i dont know who here has seen the trailer park boys when they are out in the forest searching for jacob? anyways i watched that episode about 2 hours before i started doing this and there is a part where ricky says I wanna rock out to some mitchell! so im sitting here sanding and i think I should rock to some mitchell as a joke, i turn on the radio to Q107, and low and behold the next song is "go for a soda" the same one from the show wierdddddd
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/mitchell.jpg

Step 3
-Get your 800 1500 and 2000 sandpaper and throw them in the plastic container and fill the container with some soft water, none of the bushleague hardwater we have up here in Georgetown, cause thats just gonna deposit shit into your light which is no good! Fill the thing up with water and let the sand paper sit in it for a couple minutes to soak up the water

Step 4
-Start sanding with the 800 grit horizontally. Sand that light like you just got chickenpox all over your body and the only way to make it go away is to rub the light, i honestly sanded with the 800 grit for over half an hour making sure i got every single spot on the light at least twice, its the only way to get rid of hte scratches from the 320 cause otherwise your gonna be left with some nasty marks at the end making your light look nearly as bad as the first place. Rule of thumb, once you think your done sanding, sand over the entire thing again.
-Make sure your constantly pouring some of the water from the container on the light to clean off the milky residue that the 800 will be leaving behind, also wash off the paper in the container periodically when it starts getting milky again.
-Once your done and i mean really actually done not just thinking your done, wipe the light with a wet rag and then dry it Your light when done with the 800 paper and dried should look something like this
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/800dried.jpg

-A good gauge to see how well your doing is to look and see that most of the variences in texture are consistent, ive got a few small spots that arent exactly equal but its pretty damn close, and my arm is nearly about to fall off.

Step 5
-Take the container with the sandpapers in it and go to the tap, and rinse it out and wash off the other sand paper to make sure it doesnt have any of the nasty milky crap from the 800 left in it. Rinse that stuff out and fill err up again its 1500 time!

-Sand once again with the 1500, this time vertically again (its important to switch directions every grit because it works against the old scratches getting rid of them) Wet sand with the same technique again, making sure your getting rid of the milkyness, i just usually cup my hand into the water and throw some on the light as i go along.
-Sand until you think your done, then sand over the entire light once again
Your light will hopefully look like this or better when its wet
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/wet1500.jpg

and like this when its been wiped off and dried (I always see it dried to really tell where the scratches that need to be sanded are to make sure im doing a good job of it)
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/dry1500.jpg

Step 6

-Take your container and clean it again! ONLY 2000 GRIT TO GO!

Step 7

-sand that thing horizontally now hardcore once again with the 2000 gritt "sand sand sand the light, making sure to press hard, get your daily workout done, so you wont become a tub of lard"

it hopefully will look like this wiped off and dry
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/dry2000.jpg

Step 8

-Rubbing compound! I personally used turtle wax cause its easily available at Crappy Can. Get your shammy and follow the instructions on it (damp the cloth, rub it in in circular pattern, use a generous amount contrary to what the thing says, then buff it off with another cloth)http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/rubbingcompound.jpg

I did 2 sets of compound aka compound and buff once then compound and buff again. It looks like this.
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/aftercompound.jpg

Step 9

-Time for the plastic restoration stuff
-Shake that stuff up good and apply it to your buffer of choice, using a polishing pad, you can use all different types just make its one that is made for polishing. If your using a rotary tool REMEMBER LOW RPMS' YOU CAN MELT YOUR LIGHTS!
http://img.photobucket.com/albums/v172/doofy500/lightrefurbish/polish.jpg
-does anyone notice the little face inside of the Plastic cream on the pad...man im tired....
-Work the stuff in with the weapon of your choice in a circular fashion, keep on rubbing it until it nearly all disapears. Trust me it takes a bit but eventually the stuff will all work it's way in.
-Rub off excess and check for bad spots, Re-apply the plastic restoration stuff and work it in once again, I actually did 3 sets on each light to make sure it was really really well done

Step 10

-Take a buffer, i used one on a drill and buff the stuff up!
-take a rag to any spots that still look a lil foggy
YOUR DONE!!!!!!!!

Now this way of doing your lights is by no means perfect, because of course eveyrthing your using on the lights has texture, your going to be left with some very very very small swirl marks from buffing etc, however for the most part the majority of the sand paper scratches will be gone, there might be a few in some hard to sand areas however it should look pretty damn good.

A reminder of what it looked like

Triple S: Sick Sh*t Scott! Came out real good. Is this what you did all weekend up North? haha. Your car has come along way since I last saw it. You'll have to help me out with mine next summer.

The only critisism I can think of is that you probably could have saved a couple hours by taking the bumper off. None the less, your lights came out looking pretty Gude.

not sure how this would have saved time? Unless that was a joke?

anyways it worked pretty good

I believe it would save a bit of time since you woudln't have to worry about scratching the bumper and it is much easier to reach the corner bit that's sort of hard to reach due to the bumper.

But taking the bumper off itself is a good 10-20minute workout anyways.

In the end, probably just makes it easier on your arms working from an upward position rather than sideways.

Great how-to though. You did a good job on them.

Pretty much what Mp5_ToFu (http://www.toprotege.com/forums/member.php?u=4191) said. Once you've taken your bumper off before, itd take litterally like 10 minutes to take it off again (first time took me about an hour...). You wouldnt have to tape around the lights and you could even take the entire headlight off the car and watch the boys in blue with a beer in hand while scuffing the lights.

Another "+1" on that...most of you guys saw my front end ripped apart. The biggest advantage I found (beyond not having to worry about scratching the paint) is that I can sit in a comfortable position wherever I want to do the sanding...and yes it is easier to get to the corner bits to get that all even.

BTW, great how-to :goody:

WARNING

I just took a look at my lights today, and the definitely arent as nice and shiny as they were yesterday, possibly the rain had something to do with it, im going to have to polish them again harder this time hopefully they will come back

Did it just haze up?

It would probably mean you didn't wash all the polish residue off or break it down properly at the end.
Be sure to work in the final stage of polish well. and soapy wash inbetween and at the end of different level of compounds (since it's a quick thing to do).

If you THOROUGHLY did this.. then I'm not sure what it would be, but best of luck

AKRISONER
October 16th, 2008, 06:49 PM
so? what exactly should I have done? Made sure i worked in the polish more? or buff it better?

CulRidr
October 16th, 2008, 06:53 PM
how harsh is the compound considered to be? The stuff I used worked instantly with very little effort - using a "cutting" pad - I was able to bring lots of shine from a grit level of 800 (or 1000?) just for testing...

AKRISONER
October 16th, 2008, 07:06 PM
hmmm a cutting pad might be the way to go, i was using a softer polishing pad, but i think with my next go im going to use one with a bit more grit to it, hopefully that will get err smoother.

CulRidr
October 16th, 2008, 07:14 PM
you shouldn't NEED it, but it would definitely help

Mp5_ToFu
October 16th, 2008, 07:58 PM
You should have rubbed the polish in longer. Polish is basically tiny particles that disintegrate as they take out chunks of the surface to make it smoother. In theory you could have left a ton of microscopic divets filled with tiny polish particles.

Just try giving it a good wash first. If that fixes it, then what I've been saying is right. Otherwise just polish it for a good long time. Just keep rubbing it in... (also known as buffing). I'm not sure what you're referring to when you say buffing :p.

AKRISONER
October 17th, 2008, 09:50 AM
well i used the mouse sander with a light polishing pad and rubbed that in for a good while, then i took a buffing thing on the screw driver and buffed the entire thing.

Mp5_ToFu
October 17th, 2008, 09:53 AM
Buffed.. with?

just cloth and no polish? or wax? or...

Basically all you do after you 'polish' is to give it a good clean.
Have you been able to go back at it again? results?

Looks great.

My GF's P5s headlights looked the same, you could barely see inside of them. I spent ~1min on each with the buffer and some pre-cut cleaner and then using the terry to buff it out, and I literally saw 90% of the results you got.

I'm fully aware of the all-out process, but for the lazy, a random orbital and 2-3 mins of your time and you can get them almost perfect. She almost fainted when she saw how easy it was.

Myk
October 17th, 2008, 01:49 PM
You should take the headlights off the car. When you sand, you always sand past the area where you are working. The inside corner, where the signal is, won't come out 100%.

This isn't a 100% fix, but it will be way better than before.

Good thing about sedans, is that e-bay headlights are very cheap and readily available.

How long did this all take? in reading this i Would guess 3-4 hours total?

Ok cool thanks man

My dads headlights on his caravan are sooo clouded it will serve as the perfect test ground lol!

CulRidr
October 20th, 2008, 01:12 PM
BTW, I did this to my tail lights yesterday, and the plastic is SO much softer. What that means is that you can easily do both tail lights in around an hour or so (I did). And since the plastic is so soft, every step takes MUCH less time, and it's easier to get rid of all the scratches!

Mp5_ToFu
October 20th, 2008, 01:31 PM
So AK, what is the final word. are yours still re-hazed up? or did you fix it.

00bluees
October 20th, 2008, 06:47 PM
did this to the headlights on my neon. used 400, 600, 800, 1500(lost my 1000 somehow) 2000 then rubbing compound. came out 98% perfect. i'll post some before after pics. they were nasty before but almost brand new looking now. they are starting to deteriorate on the inside of the lens hence not being 100% shiny. took me an hour per headlight to sand and buff. used turtle wax rubbing compound and mothers foam (original) powerball (not the powerball 4 paint)

will post pics of results soon.

EDIT FOR PICS:

after car wash, before any sanding etc.

its actually kind of wierd, I had to polish mine with the full blow polisher like 3 times, Then I hand wiped them with polish 2 times, and now they seem to be fine all the time. I think the light needed to build some kind of new layer. The things look clean all the time now, EXCEPT FOR THE NEW ROCK CHIPS DAMN YOU 401 TRUCKS

Give this a try. Apply that plastic polish and then buff it in. Then turn on your headlights and let the lights in a way, bake the plastic. After the lense is heated, see if it turns back to the yellow. If it doesn't, its beneficial because in a way, the plastic restoration gel has been baked back into the lense.

If anyone's interested in protecting their headlights after the refurbishing, I will be participating in a groupbuy for the Xpel Headlight Protection kit over at themazdaforum.com.

it might be a property of the plastic, I don't think it's a coating.

If it was, it wouldn't go opaque.

AKRISONER

yea its fine man, All I notice is a slight fogging every once in a while. Basically once youve done the job ive found that I had to polish, then it went foggy then i polished again and it went foggy again then i polished again and it holds, so basically you rebuild the front of the lenses to get them nice and smooth again from the very small stuff. I havnt polished them since what august and they are only a little bit foggy now, but its nothign compared to the moister i have in my headlight now :(

Someone mentioned the headlight covering.

I would suggest the 3m film like Lamin-X after this is done.

Mine weren't clouded, just pitted and looked like shit. I did a light polich to have them look better, and then applied Lamin-X film on my fogs and lights.

After a few days for the film to set itself, they lights look new and I dont have to worry about re-polishing or pitting.

Mine have never gone cloudy/hazzy since I did it last summer.

And iJay, just so you know, the smoked ones would be illegal.

Thanks for the info, took a quick route and used only 1500 and 2000 grit sand paper then turtle wax the heavy duty stuff. then i finished with miquires Plastx which Reaallly did an awesome job getting them shinny again.

thanks again

I usually use some Polishing compound after sanding.. and then lastly some Plastix to top it off.
