Moving this post onto the "ask an expert" thread:
I've read a lot of posts about films and coatings and noticed that most folks use film as protection against rock chips, presumably from freeway driving. For that reason (and to save money), some people do front-only or partial coverage. I drive mostly on secondary roads at 30-50mph and don't have many chips on my car even after 10 years. Are front films less useful for suburban speeds? If I'm going to invest in film, I'm wondering if I should be focused on the side of my car instead of the front? You know, to protect against runaway Home Depot carts, uncaring Escalade drivers, or even just minimizing damage from mis-judging my garage entrance, versus the damage from the less frequent flying freeway rock? How does film stand up in a parking lot against an adjacent car door? (I don't mean someone seriously trying to ding me, I just mean ordinary wear and tear from sloppy door-openers). For the discussion, please assume I'm going to do a full vehicle coating in addition to some/all film coverage, because carwash swirls and bird poop drive me nuts, but I won't obsess over a couple of small dings on a lower valance.
