Paint Cure Time/3M Paint Protection Film

My new M3 (Jerez Black Metallic/Silver Novillo/Competition Package is set for Performance Center delivery on March 22. Am I excited or what? Here's my question (actually several questions): I am considering having Extreme Colors in Greenville, SC, do the 3M paint protection film on my vehicle. Question 1: Can anyone comment on the quality of work done by Extreme Colors? Question 2: Does anyone know what BMW recommends in terms of time before it considers a vehicle's paint to be cured? Question 3: Is the film more apt to be visible on a black car vs. a lighter colored car?

Thanks in advance to all who can shed light on my questions.
