There are “kits’ to use to polish those headlight covers.
BUT-—I was told that really soft cloths & TOOTHPASTE does just as good a job.
EVERYTHING I have has old fashioned headlights-—about $7 for a new bulb-—and easy to replace.
I know there are ways to polish the plastic headlight covers.
The point is not to be cheap but to achieve excellence. New head lights are not all that expensive and the change in appearance is dramatic.
