Getting a stone chip in your windshield can be very annoying.  Also, in many places your car won’t pass an inspection if there is a chip, as it can affect your line of vision.  If you deal with the chip right away sometimes you can avoid the crack from spreading.  I was driving one day and got a chip so I had my repair shop call in a windshield repair specialist.  The specialist inserted some resin into the chip and now I can’t even tell where the chip was!  If you leave the chip and there is a big temperature change the crack can spread at different angles across your windshield.  Your windshield is also a safety feature of your vehicle.  In the event of a crash, the windshield will help keep the occupants inside the vehicle.
