Yep you get what you pay for, I like the rap on the inside but not for me on the outside.
Just spend the money and get the BMW factory parts to complete the black look around the window you will be so happy as it will last and look great.
Yes OK it is not cheap but for around $1100-$1200.00 i think its worth it, do it once and do it rite.
Other wise every time you clean your car you will be annoyed when you see lifting and pealing of the sticker
our Aussie heat kills every thing.
