Get it fixed before some of these grow can cost you a windshield. Many
insurance companies will waive the cost for fixing a glass nick. On of
many companies (including ones listed in your local yellow pages)
should be able to do this. Safelite is a cheap outfit, other people
prefer PGP so YMMV. BTW, Boeing uses PGP windshield glass, but many
European luxury cars come with Pilkington (UK?).
