ok, so there is a crack in my windshield that i have noticed, its like the size of the dot on an exclamation point maybe double the size of that but fairly small. I also have the windshield tinted so im wondering what can i do in order to stop it from spreading, im going to the GM nats and i dont want that to happen

 

If its small take to glass shop they can fix it I got one cant even tell where it was.I think it was 50.00. It will spread if you let it go.

 

Glass shop as suggested is the best bet. I think the old school trick was women's clear finger nail polish.
