Well I can appreciate and respect you for wanting to keep the frontend of your car in good shape during your trip but you can get stone chips just going to the store. I like the idea of the 3M stuff but if you decide to just go w/o it, do a good 3 step wax process and bring along some WD40 for the bug removal. Also your going to want to hit a couple touch free car washes along the way too
Here one of my mottos for keeping your car clean, "clean as you go, no matter where you go"
