The star break is the break wherein the damage features multiple cracks running from a central point of origin, or the impact point. Depending on where you live, the cracks extending from the centre of the break may be called fingers or legs, both of which mean the same thing. These cracks are troublesome because they have a noted propensity for rapid expansion: the sharp edges of the fingers tend to probe further and further into your glass due to air and material tension, and this results in the cracks running longer every day you leave them in your windshield. Thus, star breaks should be brought in for windshield repair as soon as possible to avoid exacerbation of the problem.
Now part of the problem with the star break is that it can be quite difficult to get the resin as deep as you would want into all the fingers and minute fissures of the wound. What a lot of professional windshield repair gurus advise is that car owners doing their own repair bring in their cars to the experts for breaks aside from the bull’s-eye type, which is often the type meant to be repaired by the simple DIY kits available on the market. If you are the stubborn type of car owner, however, you may try out another technique for working the resin properly into your star break: join its fingers until it looks almost like a bull’s-eye.
A good number of auto glass repair technicians do this: they take a small, fairly sharp probe, and then use that to tap the glass lightly over the break. The tapping is done in such a way that additional breaks are made. How can this be a good thing? In that the breaks created are actually minute cracks joining the fingers or star breaks to each other, to make the resin application simpler and easier. The looping does not only relieve the stress that is responsible for the crack’s expansion, it also facilitates the penetration of the resin once the DIY windshield repair kit is applied. Take note that it may not be necessary to loop all the cracks to each other. Some breaks only require a few loops, almost half and quarter loops of several fingers.
Once you have done this, you may move on to the usual steps of windshield repair. Take the bracket and use it to apply or inject the glass repair resin into the area of damage, letting the injector do the work. Remember to do this out of direct sunlight, or you may end up with the repair curing too fast. Depending on your preferences, either use sunlight or a UV lamp to set the repair once it has been injected.
