DIY: Headlight Restoration using Clear Coat
Video tutorial on how to refinished hazy/foggy plastic headlights by applying clear coat. This is intended to be a long term method compared to the other two methods which I have done in the past that was the wet sanding/polishing method and the method using strictly toothpaste. The headlights do not need to be removed from the vehicle or disassembled as I have shown the in the vehicle. Removing the headlights from the vehicle does help to eliminate the chance of any over spray from the clear coat or adhesion promoter landing on the paint which would need to be cleaned afterwards.
Tools/Supplies Needed:
-800 grit wet/dry sandpaper (if your headlights are severe)
-1000 grit wet/dry sandpaper
-bucket of soapy water
-isopropyl/rubbing alcohol
-clean lint free cloth
-tape
-paper
-adhesion promoter
-lacquer/clear coat
Procedure:
-if you decided to remove your headlights, start with that step first (headlight removal varies between makes/models of vehicles)
-wash the headlights thoroughly to ensure no contaminants will get into the wet sanding process
-tape off around the perimeter of the headlight lens or vehicles paint to protect it (optional)
-ensure the lens is always well lubricated during the wet sanding process using the soap water
-if your headlights are severely hazy/foggy, wet sand starting with 800 grit and finish with 1000 grit
-if headlights are mildly hazy/foggy, start and finish wet sanding with 1000 grit sand paper
-once satisfied, wash the headlight again to ensure there are no contaminants which would affect the lacquer/clear coat
-once headlight is dry, wipe it down with isopropyl/rubbing alcohol
-tape off the areas you do not want any lacquer/clear coat on
-wipe headlight lens down again with isopropyl/rubbing alcohol, do not touch the lens with your hands (oil from your skin can cause imperfections when apply the lacquer/clear coat)
-use the adhesion promoter to ensure there will be maximum adhesion when applying the lacquer/clear coat
-once adhesion promoter has setup, then go ahead and apply the lacquer/clear coat
-lacquer/clear coat can be applied in 2 coats if you are not planning on wet sanding afterwards
-if you are planning on wet sanding to a polish afterwards, apply 3 coats to ensure there is enough material for the next process

-let the headlight fully harden in the sun for at least 24 hours before the wet sanding and polishing stage

Nice tip for a DIYer.
One tip...being a painter.....if I did not want a tape line showing where I shot the clear to my light....and this tape line could be seen....I would untape it when I got done spraying the last coat....CAREFULLY.... so this line would 'lay down'not have a sharp edge when it dries.
I use a specific coating product made for this problem with lights that get foggy/dull.

This is great stuff if your needing to get your lights so you can drive safely at night again BUT Corvette owners need to know this will not get your lenses restored to looking new again and certainly not back to show quality. Crazing happens between the two layers of lexan in the lenses and all the sanding and polishing in the world will not affect that.
There are services out there that will remove your headlights and install new lenses for $450 parts and labor. At $225 a headlight is that not better than all this sanding, polishing and painting... if you accidentally scuff up a fender the repair will run as much as doing the headlights

I agree. Some people are often times looking for a fast quick weekend repair they can do themselves. Not every car is the same and result may not be as some may think they should be.
Like I wrote before,...I use the clear that is made for this repair that seems to be a bit stouter in scratch resistance.
In your second split photo...it appears the red car on the right is not the same car as the red car on the left due to the headlight area is not red...it is black.

I agree DUB. Just wanted to let folks know about it. First pic the car had a wrap on it which was removed right before doing lens replacement. The red cars inserts were switched out for black ones during lens replacement. They had a special at Christmas lens changes for $350. Can't reveal company as they are not a "forum vendor".
