Crack Eraser.com long crack repair tools have small 13/8" suction cups that use a thin grease to lubricate the suction cup to slide along a crack during repair. When performing long crack repair use a liberal amount of this grease on the suction cups to prevent the suction cups from sticking and causing the crack to flex letting air re enter the crack after injecting it.
The 1.75 oz size has enough grease to perform 100 or so repairs. It cleans up easily after repair and is great for chip repair also. Most of our technology is designed to work for chip repair and long crack repair. We have spent years working out the bugs and creating what we feel is the best windshield repair system in the world.
