A nice paint polish and wax job always looks nice but you never get a dramatic improvement in appearance as you do when restoring hazy headlights. 16 year old Jetta.
I took it a step farther. My 14 year old headlights were hazing on the inside. So, I installed one new light assembly, and my son gave me one that the body shop was throwing away. It still looked practically brand new. A customer wanted aftermarket lights and they didn't want the removed lights. Another employee wanted the other light.It's like a teeth whitening job for the cars face.
500 sandpaper dry, then 1000 and 3000 Trizact pad wet topped with 3M headlight coating.
That's... what 3M's headlight coating is for.In other words, you removed the clear coat from the polycarbonate lenses. So no UV protection anymore.
