Paint experts ? Chalky paint ?
That paint wasn't oxidized! Looks to me it was at a storage facility for a while. Just plain dirty! I even notice the dust used in fingerprinting on the door.
Safty-Kleen offers excellent detailing chemicals. I think if there is an issue with the clearcoat it can be buffed out as long as it isn't cracking or scratched.
Clearcoat is a catalized product. If it fades it is more than likely a bad run of the product. It is polyurethane so its like having a thin plastic coating once cured.
I have also seen No Touch car wash chemicals destroy auto finishes.
