Generally speaking the old "wait 30-60 days to wax" rule has become obsolete when it comes to factory finishes. Some body shop repairs do still require a waiting period because those materials aren't "baked" in the same way paint is at the factory, and thus will continue to out-gas as they cure -- though even that is not a 100% rule anymore as technology and chemistry change over time.
I hope so because I'm doing the CQFinest this week and I picked it up.at the dealer a week ago fri.
Factory paint is almost always fully cured by the time it reaches the end of the assembly line due to the way it is formulated and applied; not to mention that all C7s are 'quarantined' at the factory for two weeks before being shipped out -- it's most likely already a month old by the time you get your hands on it.
You shouldn't have any issues at all with your CQFinest install; be sure to post pics when it's done!
