Windshield repair doesn't actually remove any of the damage; it merely masks and strengthens it. A successful windshield repair involves cleaning the surface of all debris and foreign objects and then injecting a special resin into the damaged area. This resin is then put under a UV light (or just put out under the sun) to activate the curing agents in the resin. Once cured, the resin becomes crystal clear and is much less visible to the naked eye; however, it's important to understand that every repair will look different when the work is completed. Time passed and prolonged exposure to weather and dirt will make the repair more visible, so it's best to have the windshield repaired as soon as you notice damage.
While a windshield repair will be less visible once the repair is completed, the purpose of the repair is to save the cost of replacing a windshield. Once filled properly, the damaged area of a repair will be stronger than it was before it was cracked. Some companies simply squirt a resin into the impact area and never fill the cracks; this completely nullifies the purpose of the repair. If all of the cracks aren't filled, it can still split and you will then need a replacement windshield. We always fill the repair area 100%. And we always give you a warranty on the repairs we complete for you. If you are not happy, or the repair does not pass inspection, we will give you full credit towards a replacement windshield.
Yes, long cracks on windshields can be repaired; however, the truth is any damage that's larger than a quarter will not pass the Pennsylvania State Inspection. Companies that repair larger cracks will take your money knowing that you'll fail the inspection and come back to them for the replacement. This means you're spending more time and money that could have been avoided all together by having the windshield repaired right the first time.
