Thanks for such a quick reply, I was thinking the wipers might scratch it up eventually but I wasnt sure if it would be like a few months, or a few years before that happened. Well, that sucks because I know it would only be a few months before a new glass windshield would break on me anyway. Are there any other solutions? I hate driving around with a cracked windshield but I cant afford to replace them 3 or 4 times a year. If my insurance would pay for it every time it would be ok but I'm on my dads USAA policy and either the deductible is too high or they just wont cover it, I dont really know, I had to pay the total cost out of pocket last time I got it replaced. I wish there were a law that says people have to brush the loose rocks and shit off their farm vehicles/trailers before they take them back on the road.
