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 butt up to the tool at the point when using the 3-injector patented Multi-Viscosity Method and can go to the edge of the windshield. With the 2 inch leveling nut and bolt it is self-leveling. The threaded injector holds 36 drops of resin.
This tool's design allows for sliding and does not close/push the crack closed. Tools used to repair chips have too much pressure and will push/flex the crack closed so that it will under fill and spot the repair. Again it boils down to the physics of the tool: length, mechanical advantage, size and durometer of the cups.
The Long Crack Crackmaster tool is designed to not flex the glass. Flexing down on the glass when doing a long crack will push the crack closed causing an under-fill and spots. That is why this tool has a single custom made suction cup at a proper distance from the injector. The new leveling nuts allow for automatic leveling. Just push the cup down, level the injector and your ready to go.
You must have a crack-opener to use this tool. The crack-opener tool is the secret to easy and fast long crack repair. Here again it must be of proper size to allow for leverage and mechanical advantage without causing the crack to spread. Our crack-opener symmetrically opens the crack to create an overfill. You will see resin come out of the top (surface ) of the crack when you release it. That is what you want, for a complete fill you must overfill!
Repairing long cracks puts you in the repair vs replacement market. You can put an ad in the Yellow-Pages or Google Adwords and see a profit, which you cannot do just repairing stone-breaks/chips.
