When I was driving on the Pa turnpike my windshield was assaulted from a stone kicked up by a truck. My insurance company gave me the choice of replacement or repair. Since it was less than the size of a quarter and in the far corner of the windsheld (out of driver's view) I opted for repair. A few months later the crack got bigger. I called the insurance company and they arranged for replacement from the same glass company. Didn't cost a dime; however, I'll probably go right for the replacement in the future. The repair didn't work and even if it had, the sight of the crack was still visible and slowly over time started to annoy me.
