Wonder Bar Windshield Crack Repair Kit Tool Options and Descriptions:

(1) Long Crack Slider and Single Bar Chip Repair Structures.

  • Self leveling 
  • This structure slides along the crack and does not push the crack closed
  • Change suction cups to the 2-inch stiff or 3-inch cup for chip repairs

Our Crackmaster long crack repair tool slides along and injects the resin into the crack from the surface. The Crackmaster for long cracks is designed to slide from the tip/point to the edge of the windshield. With the stabilizing bolts it is self-leveling and the pressure is controlled so to not push the crack closed. Note: long cracks are surfaced.  The pressure bolt allows you to  increase pressure when needed.

This tool's design allows for sliding and does not push the crack closed. A windshield is only 5 mm thick. The outer layer you are repairing is only 2 mm thick. It will flex easily. Tools used to repair chips have too much pressure and will flex the glass and push the crack closed so that it will under fill or spot the repair. It boils down to the physics of the tool: length, compression, mechanical advantage, size and durometer of the cups. 

The two stabilizing bolts allow for automatic leveling. Just push the cup down, level the injector and your ready to go. 

Change the suction cup to the 2-inch stiff cup or the 3-inch cup and you have a chip repair tool.

(2) Crack-Opener

  • The secret to easy long crack repair 

  • Symmetrically opens the crack without spreading it

  • Creates an overfill

  • Being a wonder bar it can be reconfigured into three other tools

The secret to easy long crack repair with Ultra Bond structural adhesives is the crack opener.

Take it from the Crackmaster himself, size matters with a crack-opener.

I often use two at the point for an edge crack and four for a floater crack. 

The dimensions and custom made suction cups will symmetrically open the crack so you can get our structural adhesive crack resin into the point area of a long crack easily without spreading the crack. Symmetrically opens the crack and creates an overfill. You will see resin come out of the top of the crack when you release the pressure bolt which is what you want. Fundamental fact of adhesives is to overfill. The best from the one who invented long crack repair.

(3) Star-Leg Flexor

Often while repairing star-breaks one of more of the legs of the star will not completely fill. Since the beginning of windshield repair the method to get the leg to fill was to press on the leg with a small screwdriver or a probe and hold it until it filled. Well normally your thumb and fingers will start to hurt before the leg fills and you will let go too soon and have to do it again. No more of that, with the Star-Leg Flexor you just place the tip in the leg and turn the pressure bolt until you see it flex and then stop. Then just wait for it to fill,  let the Ultra Bond Star-Leg Flexor do the work for you.

(4) Probe 

The edge of one side of the Wonder Bar is sharpened to a point for use as a probe.

(5) UV Light Holder

When you are ready to cure the Wonder Bar also works as a UV light holder.
