If the windshield repair problem lies on the inside of your headlights you might need a more complex fix. Removing the casing is a tricky business. A professional headlight restoration service can easily remove the casing without damage and can clean and buff any scratches out of the inside as well as the outside, leaving them looking like new. You may want to shop around and for the best price.
Automobiles are made so that a cracked windshield can be replaced; they are not made to be repaired. To my knowledge, manufacturers do not recommend or promote repairing windshields they recommend replacing them. A windshield is a structural part of the body and is in place for safety reasons. You shouldn't mess with the overall safety of the car by repairing a glass that is vital to safety during a rollover or accident.
As a windshield installer for the past thirty five years, let me give you three good reasons not to repair your windshield. As windshield repair is a gimmick in my opinion.
Test your lights. If you notice an improvement-you are done! If it still appears dim or cloudy, you may want to use a special plastic cleaner and wax to give it a higher polish and sheen. These can be purchased at fix auto glass repair repair stores. When using them, be careful not to get any on the rest of the car as it could cause damage. Some masking tape around the headlight border can help protect it. You may want to use a rotary buffer to ensure the smoothest polish possible.
Once you have figured out that the crack on your windshield can be repaired, you will need a good repair kit. You can get one from your local auto parts shop or online auto parts retailers. Usually, rockchip repair kits come with an applicator or injector, an adhesive curing film, a suction cup (which serves as the base or stabilizer), and a tube of liquid resin.
The next step is to open the syringe and placing it in the pedestal. The plunger has to be pulled out from the syringe and released. The compound will be forced into the chip. The process has to be usually done about ten times. However it varies on the brand.
Windshield repair techs come and go on a daily basis. The majority struggle to survive. Most fail. It's not that they're not good at what they do, it's not that they don't have the skills, it's not that they're not willing to work hard, it's their lack of MARKETING Training. That's the bottom line: It all comes down to proper marketing strategies.
