I've been doing alot of headlight restorations as a individual service. I'm actually averaging more $/hr than detailing doing it. A coworker from my full time job had these sitting in his closet thinking they were toast. I was able to get them to probably about 90% clarity of a brand new one. I'm happy with them and so is he. Driver side before Both zoomed out After the nastiness was sanded down One done Comparison Done Thanks for looking.
You can buy both items at Home Depot. Spar Urethane clear gloss and mineral spirits. Very easy to do as I just did one last week and the headlights look brand new! Here's a link to the instructions: http://www.autogeekonline.net/forum...sealant-spar-urethane-vs-opti-coat-2-0-a.html
I used spar and mineral spirits with a folded up scots blue shop towel. 2 different sanding discs, 2 polishing discs then compounded. 2 ipa wipedowns to get any oils off then the sealing with spar. Hardest part was that they were off car. I couldnt figure out a great securement to hold them down while working on them. Sent directly from my brain.
