Is there any recommendation on the wait time before applying Zaino or any wax coating to a new TL?

Also what are the annoying things a dealer does in the preparation of a new car that I can avoid?

Thanx,

I did it immediately before it got dirty so I didn't have to do any prep work.

 

As soon as you want.

 

Immediately - before something stains or damages your paint. Modern laquers are baked and fully dry almost instantly, certainly before the car gets to the dealer.

 

You might want to clay as well since transportation to the dealer can get some rail dust and environmentals on the paint. A good clay can get the finsih smooth as glass and ready for what ever you plan to apply next.
