Windshield repair tools are used to repair auto glass that has been damaged, chipped or cracked. When damage occurs to a car’s windshield, the type of repair needed will dictate the tool that the auto repair shop will use. Simple repairs, which involve scratches that appear on the surface of the windshield, can be done by the car owner with an auto glass cleaning kit that contains a rubbing compound. The rubbing compound consists of a chemical called cerium oxide that is used to seal the scratch and prevent it from spreading.
More involved repairs that appear below the surface of a laminated or tempered windshield must be performed by a certified or qualified auto glass repair shop. When a crack, even as mall as a couple of inches, develops below the surface, it will lead to further damage to the window and result in replacement of the windshield.
The repair tools that are used to perform a proper repair of a windshield include windshield repair kits, resins, UV curing lights for the urethane sealant and pre-treatment chemicals.
Windshield Repair Kits
The windshield repair kit is the most important part of the windshield repair system. This tool is what is used to restore the structural integrity of a windshield, making it safe to be used by the motorist. The tool is important for cracks and chips that are beyond the surface and can potentially grow and result in full replacement of the windshield.
Windshield Repair Resins
The windshield repair resins involve adhesives and chemicals used on the damage and to seal the windshield. Resins are matched to the type of window based on the standards of the car manufacturer and the type of windshield that the car uses.
There are different resins for the different types of damage that can occur. For example, a windshield crack caused by a stone produces a starburst pattern that is minute in size but can be potentially dangerous for the driver. A low viscosity resin is used to fill the burst depending on the size of the burst. Longer cracks require a higher viscosity resin to provide coverage and fill the damage completely.
UV Curing Lights
A ultra-violet curing light is used by professional auto glass repair to dry the resins and other chemical compounds used in the repair of the windshield. A lower voltage light is used on smaller cracks and breaks while lights of up to 15 watts of power are used on larger damage areas.
Pre-treatment chemicals include primers and epoxy preps used to remove moisture and promote adhesion of resins. The pre-treatment chemicals are designed for different types of window surfaces, whether laminate or tempered and are specially designed to aid in the windshield repair process.
These tools can be obtained through online retailers and auto parts specialty stores that provide tools for auto glass repair.
