Driving requires you to see a lot of the road. You cannot see the whole road if you have any obstructions, even if it's small. In regards to problems that you could have with your glass, a crack could very well cause serious issues. Without proper windshield repair, you could find yourself blinded, or even risk delayed reaction time. You may not even think about a crack or divot in your glass, but that one time you do, an accident could occur.
Avoid DIY At All Costs
Do not work with DIY options. This doesn't get your glass up to code. If you must do this, you can utilize this with a simple element, and then get to a professional. Do not do this without an appointment for getting a professional to help you with the right solution. Going with anything but a professional solution will cause you to make matters worse.
Professionals Give You Results
When you pay for windshield repair, you'll find that results are guaranteed. The repairs will be on par with what manufacturers recommend, and they will pay off dividends. Don't risk your life, or your vision, go forward with a professional solution.
