What happens
 

When a paint is baked to soon after spraying, or at too high of a heat? How can I prove this being the culprit of no reflectiveness, yet still having a wet appearence?

um most paint booths have the heaters or lights turned on as soon as the painter shuts the door.....

the lack of reflectiveness is more likely cheap paint cheap clear and the lack of being wetsanded and buffed out when it got finished

do they even bake at macco?

my car was done at macco like 7-8 years ago and still shines, well most of its been repainted due to minor accidents not caused by me lol
