Making the Repair / Directions:

  1. Clean damaged area with glass cleaner.
    Dry thoroughly.
    Make sure any cleaner used does not contain any residues. It would be best if you use a medical alcohol towelette, 70% isopropyl alcohol with no perfumes or soaps and leaves no residues.
  2. Place a cloth near bottom of windshield, below damage.
    Do not allow repair compound to spill on painted surfaces, as damage may occur.
    Also place a cloth inside the Windshield below the damaged area as a precaution to protect the dash in the event that the crack leaks to the inside of the windshield. It shouldn't but its better to be safe than sorry.
  3. Punch out hole in center of adhesive disk.
    Peel backing off one side of disk.
    Line up hole in disc with center of damage and orientate disc with tab pointing upward.
    Press disk to glass.
    Make sure you press all of the way around the disc to gain tight contact with the glass. This must be an air tight seal that will hold against vacuum and pressure during the process. Especially pay close attention to the disc area close to the center of the ring as this is a crucial point that needs the best contact.
  4. Peel backing off the other side of the adhesive disc.
    Line up pedestal with disc making sure tabs match up.
    Firmly press pedestal against disc.
    Again make sure you press all of the way around the pedestal to gain tight contact from the pedestal to the adhesive disc. This must be an air tight seal, so pay close attention to the area close to the center of the pedestal.
  5. Remove cap from syringe tip and firmly twist syringe into pedestal.
    Make sure this is an air tight seal between the syringe and the pedestal. It will need to hold pressure or vacuum without leaking.
  6. Hold syringe with one hand.
    Gently pull back plunger with other hand.
    Pull back until you feel plunger hit stop on inside of syringe.
    Hold for a few seconds, then abruptly release plunger.
    Repeat process 10 times.
  7. Let entire assembly sit for 30 minutes.
  8. View damage from inside automobile (you may need a flashlight).
    If air bubbles remain, repeat steps 6 and 7.
  9. Remove syringe from pedestal.
    Remove pedestal and adhesive disc from glass.
    Use a pair of pliers or safety knife if required.
  10. Clean up excess compound with glass cleaner.
