Headlight restoration... success

Well, my neighbor's g/f let me do her Jeep's headlights for free since I'm just starting out and still experimenting. I tried some 600 wet/dry and it wasn't even scratching the surface (no pun intended). Knowing my arm would fall off before any progress was made, I ran to Home Depot for some coarser grit (150/220/300). I wasn't able to get all of the crazing out but the major damage was eliminated. I followed up with the 600/1500/2400/PB SSR 3/Diamondite Plastic Enhancer/Spar Urethane Mix. I had to remove the first application of the Urethane because it would not self level correctly but the second attempt came out pretty good. On the driver's headlight, I was rushed so I have some sanding marks from the first few grades of sandpaper. A little more time and I could've come out like glass. Overall, I'm very happy with the passenger light. I'm sure the neighbor and his g/f are happy compared to what they looked like before and won't mind the sanding marks. After all, it was FREE. From start the finish, it took about 3 1/2 hours. 30 mins was to Home Depot and about another 30 mins spinning my wheels with the initial 600 grit. :mad: Anyways I'll let the pics speak for themselves and any input is appreciated....

Results look excellent. What is that Urethane mix you use and what research have you done on it (Spar Urethane Mix)? I've been looking for a good UV blocking finish to headlight restoration.

thanks. It is Spar Urethane sealer and mineral spirits mixed 1:1. Many people have tried it with excellent long-term results. If applied correctly it will level and create a nice glossy layer. It's only my 4th attempt at using it but first time actually doing it on someone else's vehicle besides on of my own cars.

That is a major improvement, how much time you have invested?

It was about 3 1/2 hours from start to finish on this job but could have been significantly reduced had I had the correct grit sandpaper.
 
Can anyone fill me in on the steps necessary to restore headlights like that?



i know i can buy a kit and follow the instructions, but what if I want to use my own technique? what exactly needs to be done and in order to restore headlights thoroughly like that? Thanks guys!
 
Start by wet sanding with something coarse enough to remove your damage. Gradually move to a finer grit in cross-hatch patterns until sanding marks are almost completely gone. Use whatever polishing compounds you choose and seal with glaze or urethane mix.
