Protection to the front of the vehicle is of course a personal choice. Per an earlier post, I used the 3M brand. I have it on my motorcoach and SSR, with not a problem. The motorcoach has had it on for three years and no gooey or yellowing.
A friend just recently removed the film from his Corvette which had been on for over five years, understand this guy thinks perfection and there was no lines left by the material. He sold the vehicle and the new owner did not want it. I wish I had put it on my tow vehicle, Jeep. Instead I used a bra and regret it. When the bra material (vinyl or leather) gets wet and collects debris under it, it really damages the paint if you do not take it off and clean under on a regular basis. I do not use the bra anymore.
As for trying to install it yourself. I would shy away. On both vehicles, I had two guys apply it and they have been doing it for years. They told me the SSR is one of the most difficult because of the round hood. They had to stretch the material over the hood, very time consuming. Between the two of them, it took over five hours for the whole job. The material is not the cost, it is the labor. I have watched these guys apply it to numerous vehicles and it is not easy, but if a person is meticulous and has a lot of time, go for it.
Good luck :cool
