Usually it's when it is on your car and not someone else's! Isn't it funny that when that 1 inch chip is on THEIR car, it's a tiny little thing but when it's on YOUR car it is a 1 inch CRATER!!! Yep! We understand! So NOW what??? Well, I'm glad you asked..... So...you're driving down the highway, it's a sunny day, the world looks great and then from out of NOWHERE.. BAM! a rock lands right in the middle of your glass! YIKES!! OUCH! What happened to your happy day? . .
