How to restore headlights? 4 methods comparison.

I show you 4 methods that can restore yellowed and tarnished headlights. I start first by showing you how to remove the scratches. Then I do a medium and then a fine sanding which allows 3 of the 4 renovation methods to be applied. I do a chemical polishing method. Then I do a mechanical polishing method. Then another method is done by applying a clear coat. Finally I test the wipes method. Then to assess how long each method lasts, I expose the renovated headlights to ultraviolet light. Finally I compare the 4 methods in terms of visual result, difficulty of implementation, necessary tools, durability and price. 0:00 Intro 2:27 Removing scratches 5:16 Removing dull and yellowed surface 8:43 Chemical polishing 10:19 Mechanical polishing 12:03 Clear coat 15:49 Wipes 17:40 Visual comparison of the 4 methods 18:42 Durability 22:20 Summary table and conclusion If you liked this video, feel free to comment, share, give a thumbs up or subscribe.
