Clear coating flaking off how to repair

[Rhodesia]

I have a 2007 Gulf Stream Sun Voyager 37 foot gas coach and I need to control the clear coat that is flaking off, it is not pealing when you wash the coach I do know that but it is flaking off and I'm starting to have dull spots. I see to many you tube videos on how to fix this your self from fellow RV'ers but I'm looking for anyone who has ever dealt with this and how they ended up fixing this issue. I took it to a auto repair detaining shop and don't even ask what they would charge, but they recommended to re-clear coat the whole motorhome
