I'm getting the van ready for summer travels and noticed that there's a perfect little gravel chip in the windshield from an oversized piece of winter road sand. It's a little crater on the front, but the chip itself extends in a little spherical impact zone through the first layer of glass.

So, my question: I've seen those ads and received those telemarketing calls from outfits that claim they can come to your house and repair your windshield. I have the impression that they sort of inject epoxy into the damage, or something. Is this worth doing? Will it actually keep the damage from spreading and return the cosmetic appearance? Is there anything I should look out for?
