The clearguard will take the brunt of the blow and I'm not aware of any way to repair it. It's pretty durable stuff. BUT - the car itself isn't damaged. I'd rather have the plastic marred than a hole in the paint.
The mask can be replaced - a hair dryer and some time will remove it and a new piece can be applied.
I hate driving on freeways with fast moving traffic with a truck hauling tons of dirt about a half a mile in front of you. Just one pebble, that's all it takes to hurt the paint. Does anyone know how hard or soft the 6's paint is?
