I think you answered your own question, though you are understandably concerned with the lines it would bug you
more if you had nicks and scratches on your Viper. Invest in the film, you will enjoy driving the car more. I agree with Drew, but I did not have it on my first car and regretted it. Especially, behind the front and rear wheel wells. Though you couldn't see it standing or without getting down and looking at it, but over time, that area took a beating, almost to the point that it looked like sandblasting. On my new ACR, I had the nose wrapped, the front part of the hood, the fog light covers (fog light delete car) , headlights, mirrors and had him custom install (no template available) guarding behind the wheel wells. Depending on your installer, you may want to look into the different types of film. I had the more durable and heavier 3M film placed on the nose/headlights, mirrors and behind the wheels and the newer durable but thinner "crystal" film on the hood. You may want to check into some of the shops that have done the work, to make sure they know what they are doing, as the better shops know how to hide most of the edges into the seams/gaps of the car as well as body lines. To be honest, though I do notice, I have yet had one person notice the lines and most times I point it out to them.... If you only track the car, you might want to look into Tracwarp (link attached) easy to install and comes right off and provides the necessary protection.
