Excellent results. Little effort,
Verified Purchase(What is this?)
This review is from: 3M Headlight Restoration Kit to Restore Dull/ Faded/ Discoloured Headlights (Automotive)
Used to refurbished the headlight lenses on a 2005 Ford Focus.
The lights had become dull and yellowed with a very rought feel. Became an advisory on MoT test.
A corded drill and about an hour transformed the lights.
The light on the road, beam sharpness and shape are significantly improved.
One piece of advice. I started out with my trusty Ryobi 18v cordless li-ion drill with this kit. IT drained both batteries in 30 minutes. The drill needed to be on full for a long time. A corded model is a much better bet, and significantly faster. First headlight took 45 minutes on cordless with corded to finish off. Second took 15 minutes on corded.
The process is simple.
A rough sanding disc attached by velcro to the supplied foam backed attachment.
1)The sanding disc cuts away all the surface of the lenses. The result is a dull white frosted looking lense. This stage took longest.
2) Next comes a finer grit snadpaper to remove the course scratches from the first sanding. The lenses will be more like misted glass.
3) Now comes a finer 3000 grit sandpaper disc and some water. This gets rid of all but the finsest swirls in the lense surface.
4) Finally comes a foam pad with some 3M cutting compound. Again I used this with water. The cutting compound removes all of the swirls and leaves a completely clear surface. The difference is staggering.
I was preparing myself to buy two new headlights. This kit has saved me that expense.
The only gripe I have is that this kit does not come with an after treatment coating. I used a coat of Turtle Wax, and I am on the look out for a more permanent coating to avoid UV yellowing of the plastic again.
Afterall, this product removes the factory applied laquer on the plastic to get the results it does. Now it is gone, the lenses have no protection from dirt, grime, salt, UV light etc.
