Polished headlights always fog back up, I was wondering if anyone has tried coating them with something to protect the oldass plastic from oxidization? Be it spray Polyurethane or a marine coating.
i used clearcoat spray on a previous car, worked well for the 4-5 years i had it.
Crystal View headlight restoration kit from Wally World or Autozone. It's about $20, comes in a foil pouch and has a quick drying clear agent that is applied as a last and final step that replaces the old uv coating. Better than any kit I have tried yet simply because most other kits are inferior because of the reason that you mentioned. Polishing is polishing and not a long-term solution like the Crystal View kit. Try it and be amazed. I was.
I have been using SEM 21013 solaray uv aerosol for a few years with great results.
How do you cure it? Do you have their UV Light?
The Turtle Wax kit works well too. It comes with 4 sanding pads, plastic polish, some kind of spray agent (????) and a clear agent that you apply at the end. Costs about 10 bucks. The clear agent is a one time use pad, but you definitely won't use all the plastic polish in one sitting.
The SEM clear cures either with the uv light or about 10 minutes in the sun on a nice day. Just sand the old coating off with 1500 wet paper, blow it dry and clear.
I had a guy do my headlights and he sanded them down (not sure of the grit) then clear coated them with what they use on paint and it looks great. I couldn't believe it when they went from being cloudy from the sanding to perfectly clear.
