I have seen this procedure first hand and walked away shaking my head wondering why anyone would want to do this to their windshield. Plus, if you haven't had a new windshield in a while it becomes pitted and is very difficult to see in the sun light or at night. If you have picked up a crack, more than likely it's been hit many times already and is probably pitted.
To change the entire windshield will cost the car owner hundreds of dollars. If they decide to bring the car to a car shop for windshield replacement, they will spend more money. Repairing a windshield at home only takes an hour of dedicated work, and it is extremely easy to repair cracks and chips.
It will be very hard to be successful with your business until you change the way you market. When a potential customer needs a repair done, you want to be the one in the crowd waving the big red flag. You want to stand out. To do so you have to give them a compelling reason to call you instead of Joe's windshield repair.
Still no big deal? In some states it's illegal to drive with a crack in the windshield that is in the driver's line of sight. In other states it's illegal to drive with a cracked windshield at all. I'd call that a big deal.
Windshield replacement can be very expensive, and you obviously want to be absolutely certain it is a necessity before doing so. If you can get by with a simple repair, go for it. If not, make sure you take your time and go with a company that will do a quality job. The windshield replacement could cost more upfront, but the long term benefits will be worth it.
