Ouch! I was afraid of that. A re-paint of the coach is a very expensive proposition, so maybe "learn to live with it" is the only viable option.
If there is an area that is not too obtrusive where you can "test", you could try wiping the peeling edge with some thinner to see if you can remove the flaky edge and maybe smooth it out a bit. Probably a lacquer thinner will be required and thus is risky becasue lacquer thinner can even dissolve the fiberglass. If you think you want to gamble and see if you can improve it a little, ask at an auto parts place like a NAPA, one that supplies paint to body shops, what thinner is used with basecoat/clearcoat paint systems and see if you can buy a small quantity to play with. Just be very, very careful.
Even if you are successful, I don't know if it will peel some more a few days or weeks later. It depends on what is causing the peeling in the first place. But if it keeps on peeling, look on the bright side: it will all be gone after awhile!
