I carefully removed that layer with rubbing compound, but noticed that the pinstriping and decals would wear down, so I was very careful not to touch them. I think I worked on the paint for several days, it felt like I was touching up the Sistine Chapel.
I hadn't really thought about the likelihood that the paint itself has yellowed. I was thinking of it as a layer on the paint, but that's probably wrong.
