Im in for delivery, my second RS6, c7!

I have a question to you out there, how have you done, with the paint job/waxing.
How good of waxing does the car have from factory? How early should one leave the car to a detailer (not sure about the correct word here) to do some kind of a sealant/protective wax. Immediately? Or wait? Some say that the paint is not "dry"/"hardened" until couple of weeks/months and to do wax on the paint might be to ruin the beatiful job they have done.
Also id be greatful for tips on the best carschampoo available, i truly love to do some washing myself, i found the maguiars wash and wax to smell lovely and seems to be shining quite nice afterwards. But as i said, what is the best product out there?
A third question. With my last one, i pushed the pedal to the metal after 5 minutes of drivning, what i heard the engine is supposed to be ready for that kind of action. Have you guys done "engine-run ins?
Ill try to be back on friday with some early photos!


Thankful for tips.
