Update: the finish is still holding up really well. There's 3 small spots where something big bounced off the car during winter(stone or salt) and damaged the dip, but it's not noticeable and hasn't loosened. Gonna peel it all off here in a few weeks now that winter is over. The body shop we did this in has been experimenting with autoflex(prodip) and I think next shot we will use that formula and probably post a new thread before next winter.
