Its been a long time since my last post.
I bought a pair of good condition used pair of headlights so that I have the time to play around with restoring my original lights which are yellowing after 10yrs. I chose this method as I believe this is the best way of doing it which should last 3 to 5 years. If the lights are old like mine you can get back about 85 to 90% clarity as there will be slight hazing on the inside of the lens. Just like the bulbs will have a hazey layer on then when you remove them. The only way is to open up the lens which I do not want to do.
1. Wet sand with 300g, 600g and finish with 1000g.
2. Clean lens thoroughly and just before Sparying 2K Clear Coat clean lens with 100% IPA.
3. Spray 2K Clear Coat in thin coats with 4 coats in total & 20min dry time in between coats.
4. Allow 24hrs to cure. Then wet sand with 3000g to remove/minimize orange peel then finish with machine polish.
Note: weather has to be dry and not too humid or else it will affect clear coat.
