Corvette C7 Stingray and Z06 and paint curing in winter temperatures

Even though the issue of the cracking summer only tires on the freshly produced Corvettes Z06 stuck in the quality control hold purgatory outside of the Bowling Green +General Motors Corvette plant, there is also another consequence and it is directly related to the necessary paint curing time and procedures to assure the durability of the already shitty paint found on any C7 Corvette.

Even though the urethane based paint system (never mind the water based base coat)  drying and curing process is based on chemical reaction, there is still the temperature factor that has to be taken in consideration when car painting is attempted in winter temperatures.

So what is that proper procedure?  After the paint is applied, including the clear top coat, the car has to be allowed to dry for about 24 hours in temperature controlled space, this is a given but... before being allowed to be moved outside, it should also be subject to remaining in a controlled space for another 48 hours, with the temperature slowly adjusted to the ambient temperature.  There is a good reason for this, specifically related to the volatile compounds gassing off at expected rates.  Does GM follow this procedure?  Judging after available information regarding Corvette production, this is not the case at all... Again, if the paint was not shitty already...
