I have to tell you guys that today I worked on my headlights and they look brand new, better than replacing them. I used Chemical Guys headlight restoration by first sanding with 2500 grit then 3500 grit. Then I followed that up with polishing pads and the V34,V36 and then there V38. Once that was done I used the pro seal 109. Sounds like allot of work but its worth it for the results I received. I'm also I the process of using there V products to polish out my black paint and while it takes some time the results are phenomenal and well worth the expense and time that will be invested in it.
