I had 2 new headlights, which the plastic of the old SW was already a little attacked. I didn’t want to polish, because no good experiences. Now I want to keep the new ones as long as possible. Can someone recommend me a good remedy, what I can do as a kind of “protective layer” on it, so that insects and dirt etc. won’t solidify? Does spray wax, wax for the paint, quick detailers…? So coatings, which are applied after grinding of headlights to get a new UV protection are not a concern for me with completely new SW.
