3M 39193 Quick and Easy Headlight Restoration Kit, Removes Light Yellowing in 15-Minutes

Product is good,, but the box in which it was delivered was fully damaged

Var tveksam. Men blev kanon

色々なヘッドライトクリーナーを使っても、すぐ黄ばむ。。 古い車なので、仕方ないか。と思いつつ、お試しで購入。 結論。凄い。 付属の3,000番やすりで磨いただけという手軽さもそうですが、 施工してから1か月経っても全然曇らない！ 2週間ごとに磨いていた今まではなんだったのか・・・と思う位。 これはリピート確定。 次施工するときは、2,500番とかもう少し丁寧に 下処理してみようかな。

Juste exceptionnel. Conseillé par un ami, ce produit remet vraiment a neuf les phares blanchis par le soleil et les intempéries. Il est, de plus, facile a utiliser (et bien expliqué!)

Finally a product that works! Results are amazing and just as described in the ad. The kit has 3 items: 1 3000 grit sand paper and 2 towelettes soaked with special fast drying clear coat. Prior to sanding I throughly cleaned the surface with a soapy solution then wiping with alcohol. I used a 800 grit sand paper(not supplied) as my lens were very cloudy. After this step I then used the 3000 grit to wet sand before cleaning again with alcohol. Air dry with compressed air then wipe with a clean lint free paper towel. Applying the first clear coat in a dust free environment and waiting 15 minutes for the second coat. Results are worth the money spent. Time will tell on resistance of product. Recommended purchase.

I used wet sanding paper in grits 320, 600, 1000, 1200, 1500, 2000 and 2500. Only after that I used the 3000 grit and sealant from the box. And the results are very good, headlights looks like new.
