Mustang headlight cleaning
So i just did this, what a pain in the ass, I did all the stuff, but there is just so much grime burned on the lens its going to take forever, i should've start out with like 300 grit or something because i scrubbed and scrubbed and the clay just kept coming ( or whatever that residue is ). They do however look about 50x better, but I'm going to go over them again because its not up to quality control specs imo.
The question is:
How do you keep them looking good after you do all this mess? Is this something thats going to have to be done again in 40k miles or is there something I can do to preventive maintenance this shit.
