Yeah, I hear you, but actually the sand will damage your paint long
before it scratches your windshield if you use washer fluid before you
turn on your wipers. I live in Arizona, on a two mile dirt road (sand)
and had to have a windshield replaced on a 2006 Silverado because I got
behind a gravel truck on the highway outside of Phoenix. The guy came
to my home and was done in an hour. Ditto with a 96 Accord about 7
years ago. We also have to remember to replace wiper blades because the
heat and car washes damage the blades before we ever get to use them.
Cannot imagine why so many people are bent on replacing their own
windshields. If a glass shop damaged my car I would certainly not go
back there unless it was to have them repair the damage.
Once again, most insurance companies will replace your windshield
without a deductable, no questions asked, if you call them and report
the problem. I doubt if it counts against your insurance either.
Perhaps that is only in Arizona but I don't think so.
