Phares opaques et jaunis : Comment les rendre comme NEUFS et que ça tienne longtemps ?

I show you 4 methods that can restore yellowed and tarnished plastic or polycarbonate 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 varnish. 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 2:19 Removing scratches 5:05 Removing dull and yellowed surface 8:28 Chemical polishing 9:59 Mechanical polishing 11:31 Varnish 15:26 Wipes 17:12 Visual comparison of the 4 methods 18:20 Durability 21:48 Summary table and conclusion If you liked this video, feel free to comment, share, give a thumbs up or subscribe.
