Hi all sifu here, anyone is using llumar? Is it good at heat rejection and does it has any issue w smart tag? Looking at the top range pinnacle 8. Is this better or 3m crystalline better? Read from posts here mentioning that crystalline will have issue with smart tag. Some even can detect after installer cut a hole for it. I have been using ecotint raybarrier for my current car for the past 17yrs and have no issue at all but not sure abt the quality of existing ecotint films.
