On our recent 28-day eclipse (and other things) trip we took a couple of rocks to the windshield. The windshield already had two existing horizontal cracks in it, one low and one high and each about a foot long, neither of which obscures the drivers vision. I was afraid that the new chips would spread to join the existing cracks, especially as we were heading into cold weather and at the beginning of our trip, so I picked up two repair kits and put them to use one afternoon prior to a day of hiking at Natural Bridges National Monument in Utah.
We continued on our trip and have since made it home and now it's been almost eight weeks since the repair with no additional cracking, thus so far so good.
What do you think, was it worth the time to make the repair to (hopefully) avoid having a visibility issue for the rest of the trip? The windshield has 100k miles on it so I know I am only extending the inevitable, but the windshield is a heated one with embedded wires in it and I know it's going to be an expensive experience to have it replaced when the time does come.
Was I just lucky or was the repair time well spent?
