After researching the subject of headlight restoration products, I ended up with the Sylvania Headlight which I purchased from the local Advance Auto Parts store for $20. The box for the product claims that the restoration project will take less than 30 minutes, but my experience was that it took about 3 hours. I also deviated slightly from the instructions and, in retrospect, could have just as easily followed the enclosed instructions verbatim and had the same result.
The process is simple:
1. Mask off paint surrounding the headlight with the tape provided
2. Spray headlight with activator - let sit 30 seconds - wash off
3. Wet sand with 400 grit sandpaper until the headlights are uniformly hazy
4. Wet sand with 1000 grit sandpaper for 5 minutes (per headlight)
5. Wet sand with 2000 grit sandpaper for 5 minutes
6. Polish with provided polishing compound for 5 minutes
7. Spray headlight with activator again - wash off
8. Remove tape (I waited until the process was complete to do this step)
9. Thouroughly dry headlight
10. Apply UV block clear coat with cloth
I left the tape on until after I applied the UV block clear coat, but it turns out that it was not necessary. What I thought would be the most difficult step turned out to be one of the easiest steps.
