For clouded lenses - replace them if feasible. If not (Mrs. Geno's headlight housings were 600 each - whew), wet sand with 600, 800 and 1200 grit. Then spray with spray max 2k high gloss. This is a 2 part paint that mixes when you activate it. It's only good for 48 hours afterwards. Lasts about 3 years. Be absolutely certain to mask off the entire car. That stuff on your windshield makes terrible glare and can only be removed with a razor. Don't ask how I know this - lol.
