  1. I was hoping youd show a completely finished light at the end. I heard of many remedies for foggy headlights, and tried them on my older car, to no avail. Now I have a newer (used) car and its headlights are much better, but Id like to be able to keep up with them. But I wonder how well this actually works.. apparently the toothpaste trick works "perfect" but it did nothing for my old car. 

  2. If ya want professional results I'd get the 3M kit it comes with all the stuff you need, I haven't bought it, but my buddy did and he said it worked great…. Of course you could just buy polish and start scrubbing away, may take a lot longer though.

  3. I bought my car new 8 years ago. I've never polished the headlights (or any part of the car) or otherwise scrubbed at them. They've been pretty foggy for quite some time now.

    I'm sure different cars use different plastics so they differ in how susceptible they are to this, but headlights getting scratched up and getting foggy over time is normal. If you think it's only idiots who polish them then then you aren't looking at very many cars.

  4. @crazyskater05 the headlights turn like that because of the suns UV rays and oxydation. if you headlights arnt that foggy looking you could just use a dap towel and toothpaste rub in circular motion over the headlight then let it haze then wash it off if it still looks a little foggy just repeat the steps again

    Sorry, I should have been a little more clear…I remove the headlights from the vehicle first. As a side note; if the plastic has oxidized badly enough, there will be tiny "stress cracks" and distortions all over the light. In this case, you can still make them 20 times better than they were when "foggy", but they will never return to like-new condition. Hope this all helps.

  6. I usually use a D/A sander and start with 400 grit on the super-rough stuff….then work up to 800-1000 grit. Finish on a buffer. Works like a charm, but i realize not everyone has access to the tools required.
