Paint protection following mop

[Ray Singh]

My wife has a Audi A6 that was once black. It has suffered many car washes and has faded over the years.
I have just paid to have the car mopped by a body shop. They assure me that the car will need nothing following the mop and should look great with minimal effort.

What should i apply to the paint to help protect the newly mopped paint?

I have heard about carnuba wax. Any good?

Thanks
