I assume it's a modern glued in windshield? If so, leave it to the experts. I put a used windshield in my S-10 when I first got it. 28 bucks for the used glass at pull-a-part, 15 bucks for the goo . . . it's not "glue" . . . glue dries. This stuff is more like nasty super sticky tar that can't be cleaned off of anything it gets on . . . and it gets on everything! Soooo . . . after spending almost 45 bucks I had a mess on the inside and outside of the truck (not just the goo, I had shards of broken glass all over the dash, carpet and seat covers). I cracked a corner of the glass I was installing, broke the trim, and it leaked at the top AND bottom.
3 years later I busted the windshield trying to get a broken limb out of my pecan tree. I paid $141 including tax to get it replaced. They cleaned up the mess. I got a brand spanking new windshield with new trim, and it doesn't leak a drop. Now I can see much better, especially at night, I don't get wet when it rains, and my carpet doesn't smell musty anymore. I hate spending money, but that was $141 well spent.
