How To Fix Hairline Cracks in Car Windows

Every driver knows that the window of the car is the most vulnerable part, because the glass can be freely broken or scratched. Like windshields, car windows are much susceptible to indents, scratches, and hairline cracks. It can be tedious to repair a car window yourself, but not unsolvable. Read on to learn the do-it-yourself way on how to fix hairline cracks in car windows.

Steps

Inspect all windows on your car including the back window and windshield : There may be more cracks that need your attention.
Purchase a specific type of windshield repair kit called a bridge kit : Bridge outfit has suction cups at each end of the bridge that latches onto the window and are the smart option for hairline cracks on upright car windows. These outfits are available at a multicolored auto supply, a hardware, or retail stores.
Clean the crack and its surrounding area so that it is free of dirt, loose glass, and other debris : An element probe works best for the cleaning process.
Use the metal probe to create bull's-eye cracks at each end of the hairline crack : Gently tap the element probe so that the inner plastic layer of the glass isn't damaged. This prevents further widening or spreading of the crack.
Load the specified amount of resin into the injector as instructed on the bridge-kit packaging
Position the bridge apparatus, so the injector is directly above the crack : Secure the suction cups in the place. Add a resin into the crack using the injector or use the pressure and vacuum controls of the injector to stink air out of the crack while forcing the resin in. When the crack has been filled with a resin, remove the bridge from the window.
Allow the resin to completely harden and dry : A windshield repair kit resin doesn't air- dry; it requires UV light from the sun or an artificial UV light to adequately dry.
Apply a generous amount of resurfacing resin directly to the repaired hairline window crack : Use a cellophane patch, and cover the area that you just applied resurfacing a resin to. Expose to direct sunlight or UV light, and allow the area to dry. After it's dry, remove the cellophane patch and gently scrape off the excess resurfacing resin with a razor blade to make it places with the environing glass to complete the car window hairline crack repair.
Clean the window with glass cleaner
