totally worth it...had it on my previous two RSXs and have an appointment next week for my new Si. I will never own another new car without it. If you get a good installer they will "wrap" the hood so you dont see the lines of the film on the front and the sides.
YES get it. Worst mistake I ever made on this car. I have so many rockchips and on a white car, it hurts. The front of my car just doesn't look like how it should with only 8k miles on it. So yes, do it and do it quickly!
If you can afford it get the front bumper done as well - the best analogy I heard was that someone said their front bumper looks like a cheese grater - after 12k miles - mostly highway - I feel about that way right now...
I got it done for $360 even for 12" on the hood and side mirrors and they quoted me about $500-$600 for the bumper which I just couldn't afford at the time and wish I would have been able to have gotten done.
