Forrest's advice is dead-on... take the advice of your painter especially if there's some kind of warranty with his work. Just in case there's a problem down the road you want to be able to find a remedy with him in an honest way and that would include following his recommendations.
I've never seen any problems with fresh paint that's been sealed with some type of wax, paint sealant or even Consumer oriented spray detailer but from research by friend and engineer,
Paul aka
the other pc did years ago, he found no paint manufacture that recommended sealing the paint before at a minimum 30 days air-cure time passed.
That said, some will argue it's safe to use products that seal paint on fresh paint and you can follow their advice if you like.
Here's a few articles I've written on the topic and I have a new one in the works...
Don't wax your car for at least 30 days!

Then there's a classic thread on Meguiar's Online I wrote in 2004 that know one has ever challenged or provided
their own theory that counters mine...
Paint Needs to Breathe
Here's an excerpt...
Mike Phillips said:
Words mean things, just ask any Lawyer. Floating around on the Internet, and discussed for decades among car enthusiasts is the myth that paint needs to breathe.
Or is it a myth?
It depends on how literal you read into the words. If you apply the common definition used for the word breath, then "No", paint does not need to breathe. If however you take a moment to understand the idea that is being expressed with this word, then I think you'll understand why the word breathe is used when someone says, or posts to the Internet that "Paint needs to breathe".
One other comment...
Most people that are involved in a discussion like this are dealing with a car that is special to them, often times it's not their only car to drive.
When you do all the work it takes to get the car to the painter and then get it back, seriously... unless you have to put the car back into service as a daily driver immedieatly... what's the hurry to seal the surface with something that coats over, deposits itself and protects the paint.
Modern clear coat paints are pretty stout as it is and anything that lands on or comes into contact with the paint that's aggressive enough or corrosive enough to harm the paint is likely going to go right through a micron, or even sub-micron layer of something you scooped out of a can or poured out of a bottle.
Just saying...
