I always want to do this but i was not willing to test on my headlight lenses. This guy did. here is is process. I thought guy guys might want to try this. The other method involved wax and buff is only a temporary fix. I had to sand and wax and buff my light every 4 months. not so fun. I hope this will fix the light for atlease a year or two.
here is the process. not done by me..
o with the whole wet sand, polish, and seal, I wanted to try something a little different that would last longer with less maintenance. I opted to apply a “clear” on the headlights. Results are pretty good so far, I just need to test how long it will last.
What you need:
-800, 1000, 1500, 2000 grit wet/dry sandpaper
-Some newspaper or plastic bags
*Optional, if you don’t have a buffer, you can use your elbow grease and buff by hand with plastic-x or something similar.
1. Mask headlight to prevent any accidental contact with body. Take your time and try to get as close to the headlight as you can. I opened the hood so I wouldn’t have to worry about the hood. You can see how bad my headlights have become after a year without touching them.
2. Soak the various grades of sand paper in water. Sand headlights with 800grit in a horizontal and vertical motion. Do not go in circles.
3. Once complete and headlights look hazed, rise with water. It should look like this when dry.
4. Mask off the area around the headlight with your newspaper or plastic bags. Make sure you tape secure the tape down so the wind doesn’t fluff it around. I noticed that it was easier to tape when the body was wet. The plastic bags stuck to the body and allowed me to control my tape line with the plastic bag. Don't mind the paper towel, there was a hole and I didn't want to use another bag.
5. Prep the surface with a quick denatured alcohol wipe with a paper towel to make sure no other wax was left behind that you might have missed from sanding. Next take your tack cloth and gently wipe the surface to remove any dust that maybe stuck on the surface.
6. Now its time to spray your clear. I laid down the first two coats very lightly with 10 minutes in between coats. My third and fourth coat I was pretty heavy on. Make sure you cut into the corners and the bends on the lens and then spray horizontally across. What you want to do is make sure you have enough so you don’t sand it off in the next step.
7. Follow the drying times from the can. You will notice that it might have a milky color to it. Once dry it was clear.
8. You might notice that the surface is a bit rough. What you want to do is go through the sanding process again from 800 to 2000 but very lightly. You just want to make sure that the surface is smooth again.
9. Take your compound and buff the headlight so the haze is gone. Next, take your polish and buff the headlights. I opted to use a final polish to give it some more clarity. Finally I topped it off with my sealant. The sun went away when I took these pictures but you can see that they pretty much look new again
I should probably have not sealed it just so I can test it with it being exposed. This was done with readily available materials at parts stores. If you don’t own a buffer, you can use plastic-X and buff with your hand like some of you guys do. There was a slight breeze so when I was clearing I had to wait for it to stop. If you have a garage it should make this a lot easier to control. I am going to update this in a few months to see how it does. Enjoy!
i am thinking of doing my very soon. hope it help...
