Hey Rick, I've been on the fence about bringing my AW 1M in for PPF. I saw Mok's VO 1M this past weekend and was very impressed with the work!
I remember having the PPF done on my AW E46 ZHP by a different vendor and it hazed and built a yellowish tint to it over time - I eventually pealed it off. Does the film you use (Xpel Ulyimate) also show dirt/dust easier on Alpine White cars? And what type of warranty does it come with?
