Here I used the Cera Kote headlight restoration kit (about $15 from Wal-Mart) and i was really surprised at how much of a difference it made on my OEM headlights. All factory from 2002, so I didn’t expect them to turn out that great, but it’s amazing what a little smoothing and sanding can do for old headlights. I wish I had taken better before and after pictures, to be honest, but this speaks for itself!
I’ve also been very impressed with Cera Kote trim restore products before, maybe I’ll show some pictures of what it did to my engine-bay plastics. Stay tuned!
Update: it’s been 7 months so far, and still looks great. I’ll see what it looks like after a year and post pictures of that too. My car gets a lot of UV exposure since it’s not in a covered environment, but it holds up well. I think the coating you apply at the end must have great UV protection
I use a polishing cloth attachment for my circular grinder with toothpaste and it definitely does the trick
I tried this without the power tool and it didn't work very well. I have a much newer car now, but I'll keep this in mind for the next time I need to clear up old headlights.
I tried this on my old wrx and it worked great. I just bought a stiff bristled brush and then a tube of colgate and it was a huge improvement.
Didn't do much for me. I tried a few different things and they were mostly a waste of time. I did recently pick up the Sylvania restoration kits and that shit was like night and day difference.
The only trick is that their "3 step" process is bullshit. It's a lot of sanding and cleaning and sanding and cleaning and before you know it you'll be on step 12 of 3 and only halfway through. But it works and the difference at night is definitely noticable.
