All Cracked Upby Dave Shores
Have you ever been faced with two or three rock chips that were connected? If you have never faced them or dont know how to handle them, here are some helpful suggestions.
The other day a customer stopped by our shop with three pits in his windshield that were less than 1- inch apart and in a triangle formation. Each one had created a star break that had become entangled with the other two breaks.
Our technician took his probe, flexed all three breaks and found out that none of the breaks were sensitive or about to run. Putting his probe as close as possible to the pit, he flexed all the legs to open the passageways.
He then mounted his injector over one of the pits and put a drop of resin and film tabs over the other two pits. The resin and film tabs are used to keep air from entering the break from the other pits while the injector is on vacuum, evacuating the air from the break.
Next, he began injecting resin into the breaks. After a few minutes, two of the three breaks were completely filled with resin and the third break had one leg that had started to fill. At this point, he slid his injector out of the way and put a film tab over the pit that he had been using to fill the break. He then drilled into the tight break that wasnt filled and created a bulls-eye in the bottom of the drill hole to open a better passageway.
Then he created another vacuum to remove any remaining air from the break. After a couple of minutes, he put his injector on pressure and began to fill the remaining legs with resin. Once all of the legs were filled, he used his ultra- violet lamp to cure the resin in the break.
When the customer saw the windshield, he was extremely pleased. The repair looked better than he had envisioned. Part of this result is due to the fact that our technician had under-sold the job in the beginning. He didnt want the customer to think that the windshield was going to look like it had before the rock hit it.
This is not the only way to approach a break of this nature, but it worked well for us and hopefully it will give you some ideas that will make similar repairs a bit easier.
