If all you are looking for is some sort of direction to
headlight restoration. I would suggest skipping Detail King and putting a kit together yourself. It will save you tons of $. i do not know what detail King has to offer, but I am a 2007 grad of Paint Bull in MI. I went for Paint Repair, PDR,Interior Repair, W/S Repair. My business did not even touch
headlight restoration. I figured it out on my own and bought my own supplies. I now do 5-10 pairs of
headlights @ $50 a pair per week. Thats not including anything else.
Now if you are trying to learn properly about paint correction - I agree with the advise of ShowroomShine.
If you need anymore info to get started pm me.
