How to repair an edge crack using the Ultra Bond Classic Crackmaster and the new edge crack resin injector.
For those you that do not have our long crack repair kit you can use the Classic Crackmaster Bridge to repair a crack by straddling the crack, use a liberal amount of vaseline on the suction cups as you have more contact with the glass than with our long crack tool.
You will be straddling the point section of the crack with your Classic Crackmaster windshield repair tool, that is our tool that has two suction cups. You will inject the front half of the crack with this tool filled with 400 long crack repair resin. You will use the new injector syringe at the edge area of the crack with the edge crack resin in the syringe.

Step By Step Instructions, Using Edge Crack Windshield Repair Resin Injector
- Drill and tap a bullseye at the point 1/8 in front of the tip so the tip/point of the crack runs into the bullseye.
- Mount the Classic with a liberal amount of petroleum jelly/vaseline on the suction cups a few inches down the crack. Slide it back and forth to lubricate the glass with the vaseline where you anticipate you will be sliding to in the middle of the crack.
- Use 400 resin in your injector and mount at the drilled hole. Do two cycles of vacuum and pressure and leave the injector on pressure.
- Mount one crack opener about one inch from your injector at the point. If you do not have a crack-opener- they only cost $70.00, an investment that you will profit from after only one crack repair.)
- If you only have one crack opener, lubricate the crack opener suction cups with petroleum jelly in case you need to slide the crack opener a couple of inches. If you have two crack openers place another next to or near the first one.
- Now turn the bolt(s) of the crack opener(s) until you see the 400 start to enter the crack then stop.
- Now go to the edge and inject the edge crack resin using the injector syringe into the edge area, which is the first 4 or 5 inches.
- Slide off the crack and pull up on the plunger so you do not waste any resin, then wipe off the tip and put the cap back on the injector syringe.
- Now go back to the point and start sliding slowly down the crack keeping resin in front of the injector at all times. Slide until you meet the edge crack resin in the middle of the crack.
- Place a bead of 2400 resin on the top of the crack where needed and cover with the mylar tab or use whitish scotch tape which is made with mylar - see our training videos.
- Remove the crack-opener and cure the injected crack.
- Slice off the cured resin and scotch tape from the surface with your razor blade at a 45 degree.
- Clean the windshield and you are done.Tip -always wipe off vaseline with a dry towel first before spraying glass cleaner.
