3M has had these complaints (yellowing) for years. I and many Corvette owners as well as many exotic cars used Venture Shield, it forms better and never yellows. Had it installed on my Z06 and it was perfect for many years. One major factor with any clear film is how good the installers are, that can make a big difference in how many problems you'll have down the road, top notch installer will tell you this is what they have to deal with all the time (lousy installations). My Evora isn't having any problems with the Star Shield so far but if it does after the warranty is off, I'll replace it with VS. Success!
