True Brand headlight restoration kit #t601
This is by far the best kit out there. I have probably done over 300 vehicles myself with this product. (Used car department of a Honda Dealership).
The buffing and clearcoat method is flawed. It will look good for a while but the will yellow again.
This stuff is basically a wetsand and clearcoat process but replaces the UV coating you remove when sanding with a superior UV coating in the clearcoat you apply afterwards.
It will make yellow oxidized headlights look just like new again if done correctly.
The shop I work at now was doing the buffing method and it really doesnt even compare. I showed them the method I used and it was night and day. Crystal clear clarity.
