Recently, there has been some debate on the forum about how to terminate long cracks and if they are worth the attempt to repair. Delta Kits follows ROLAGS (Repair of Laminated Auto Glass Standards) in all areas of windshield repair repairing damage, which recommends that any piece of glass with damage longer than six inches (the size of a dollar bill) should be replaced and not repaired.

Check for moisture and clean out the pit using your scribe. The end of the crack is not always where it appears to be, so it is significant to find where the crack actually ends. Do this is by using your scribe to gently flex the glass while watching carefully for any movement that will help you locate the very end.
Often you will find that the crack is longer than it appears when you are not flexing the glass; take a marker and make a mark about one thirty-second of an inch past the ending point of the crack. Next, using a Delta Kits 26020 tapered tip bur, drill a 0.042″ deep hole (approximately 2/3rds through the first layer of glass). If you drill too shallow you will not get a good mini-bullseye. If you drill too deep you will drill…. Continue Reading
