windshield crack repair?

My friend has a 2001 saturn sl2 w/ a cracked windshield[3/4 across the center approx. 18'' long] Is there a way to fix this while in the car or does he need to replace it?

That's a pretty big crack. A friend of mine drove around for almost 6 months with a crack in his SL2 for about 6 months before water started to come through. He didn't even bother trying to fix it though...he just replaced it. He's a cheap ass so I'm sure if there was a way to fix it without replacing it he'd've done that. But I can't say for sure.

Only bulls eye type stars and little chips can be fixed, so long as they are less than 1/4 inch across. Everything else including all cracks, and chips that have started to crack, cannot be fixed.

Your buddy needs a new windshield.
Personally, I usually buy a new windshied at a glass shop for about $100 Canadian, and get a glass guy to install it for $80 cash.
Getting a glass shop to do the whole thing is about $250-400. They often gouge the price because most windshield jobs are insurance jobs.

Yea those prices Canadian are about the same as US. You could do it for real cheap if you find the glass at a junkyard, and succeed in removing the glass without damaging it, and get all of the adhesive off. That's a pain the balls though, so I'd recomend just buying new glass. Peace-
