First of all:
:welcome: ...to AGO!
In a week I am taking delivery of a new Black C7 Corvette.
Congratulations...
I have no doubts that you're gonna love it!
I plan to not have the dealer wash it, bring it home, wash and clay the car, and then use Rejex to protect and shine the paint.
Sounds like a good plan.

rops:
One thing I'll add is that:
Whenever I clay, I'll also use, at the very least,
a mild polish...like Meguiar's M205...before the
application of a Sealant-LSP (Rejex, in this case).
I was told instead of Rejex, use Blackfire Coating Prep, then Blackfire Crystal Coat, and then the next day Wolfgang Deep gloss Paint Seal.
You'll get a zillion different suggestions
on which LSPs are the best.
However, IMO:
If you're not well-versed in the Coating-LSPs arena...
I'd suggest that you stay within the Sealant-LSP
category for the time being.
I want to do everything that I can to protect against swirl marks.
Find out all you can about the proper methods
to wash/dry a vehicle. That's where the majority
of swirls usually come from.
