Hey Jerry, have you ever had the windshield pits repaired, like they do for pits in our car windshields ? I thought it worked great and saved me from having to buy and replace a windshield several times.

At the Mr. Car Wash places here in Houston they have a guy on duty that checks every car that comes in to get washed for for pits. I asked him if he would come out to the bus barn, some early morning and he said sure. He repaired 6 pits and I haven't had a problem with any of them since. Course I have gotten a few more now, so he will probably have to come out again sometime.

Their are Glass Repair Vans that come out to your location as well for these repairs.

Just a thought instead of replacing.
