I have the Scotchgard on the entire front of the truck, the first 6" of the roof above the windshield, and up to the bottom of the moldings on the rockers the entire length of the truck. over 6200 on the truck and drive a dirt/gravel road every day and half of the city is torn up in prep for the Superbowl, not a scratch all the soot wipes right off. only wish that the installer went up a few inches higher, the molded Mopar flaps are a bit taller than where it applied so a small strip of molding tape on the flap holds it to the body, it wont rub since its attached, and makes the instal a bit cleaner. The tape can be picked up at most automotive repair shop suppliers.
