You mean
this?
Not to sound like an ass but you're going to get chips, scratches, dust, dirt, etc. all over the hood and windshield regardless of what you put there. Traveling on any sort of highway/interstate is going to do this over time. People are quick to blame manufacturers for using "cheap paint", but really any sort of gravel debris smacking your car at 60+ mph will do that.
I was OCD about the same thing when I first bought my car brand new. I kept my distance from tractor trailers, salt trucks, pickups, etc. But over time I just accepted the fact that I'd get blemishes all over it because I travel on the turnpike frequently. On any given summer day there's tons of moth and bug guts caked onto my front bumper regardless of how often I wash it.
If you really want to care for your car's paint job simply wax it on a regular basis. Even then it's not going to completely protect it, but it'll at least provide an extra layer of protection against the elements. In the end you gotta remember that it's not some driveway trophy that needs to be polished everyday. It's just a frickin' car and it's meant to be driven!
