I used the static cling tint on my rear upper halves and it's been great. They've been through 2 summers of use now, and look just as good as when it was installed. I was going to buy new ones through the dealer, but they're about $250 ea, and this only cost me about $20, and an hour or so of time. Now it might help that I only run the half doors in the summer, but I'd certainly recommend it as a reasonable solution on the cheap.
