Waxing a car can't damage the finish, it anything it does the opposite and protects it. No offence but with how well you maintain your car it's surprising to me that you haven't ever waxed it.I haven't done anything other than washes. I just wasn't confident, fearing I'd do more damage than good. I think the previous owner polished it as there was some white residue along the edges.
If you look at my initial photo closely, you see those weird vertical streaks. Not even sure what that is.

Wax and polish provide some protection. Ceramic coating offers more, but the paint needs to be cleaned with polish before applying@theterminator93
That sounds concerning. There's no peeling anywhere currently. I'd rather keep the dullness before I risk damaging what's left of the clearcoat.
Would it be safer to put something shiny on top of what's there now? Some sort of shine detailer?
Then move to a cleaner wax. It's possible that Terminator was correct, and the clear is starting to oxidize. Even if so you should be able to make it last longer with the steps I have above. If you rub a small area really hard with the cleaner wax and it doesn't get better, you know it's permanent fading. I'd tell you to we sand it, but knowing Ford clear coat of the era, there may not be much good clear left.Tried a clay bar. Surface is smooth, but absolutely zero effect on those dull streaks.
