Sold under many brands, be sure it is the 3M product. I recently looked at a white, 18 month old 350Z with yellowing on all the 'shields" (except the factory installed, in front of the rear wheel opening). Not pretty.
OTH, my wife's 01 silver VW GTI VR6 has the 3M film, and looks just fine after 3 years.
Really not noticeable, until you look for it
Requires experience to apply properly...
