Windshield Long Crack Repair:

5. Applying Curing Strips
   After applying resin to the full length of the crack and all of the air has been removed, start at one end of the crack and reapply the repair resin along the full length of the crack. Place curing strips over the resin as you go, and lay them onto the glass in the direction you are going. Use as many curing strips as needed, and be sure not to leave any air pockets under the curing strips. No pressure is necessary when applying the curing strips, just lightly place the strips on the glass and the resin will pull them down to the glass.
   
   
6. Curing the Resin
   Move the vehicle to an open sunlight area in direct sunlight and let sit in sun for 15 minutes, or a minimum of 1 hour on cloudy days. Resin will cure from the natural UV light from the sun. Optionally you can use an ultraviolet light to activate the UV agent in the resin and begin the curing process.
   
   Allow the repair resin to cure completely before removing the curing strips. If the repair resin is still liquid under the strips, leave the strips in place until the repair resin cures. It could take an hour or more on cloudy days or with a week UV light.
   
   
7. Finishing Touches
   Once the resin has cured, remove curing strip by carefully peeling them away from windshield.
   
   Then gently scrape the resin from the surface of the glass using the safety razor with the blade at a 90 degree angle to the glass.
