So you are driving down the highway, and a semi truck pulls in front of you. Then out of nowhere a small rock, the size of your pinky, slams into your windshield. And like that, you have an expensive fix on your hands. The benefits of repairing that rock chip in your windshield is two fold. If you don't, that little chip can turn into something much worse, if you don't, it can also cause you to have to replace the whole window. Because of this, and because most people aren't made out of money, it is always a good idea to fix these before they get worse.
One of the benefits of repairing that rock chip in your windshield is protecting that chip from turning into something much worse. That rock chip is liable to spread over the whole windshield and turn into something much worse. Because of the amount of pressure the windshield is under, a little rock chip can cause an incredible amount of damage beyond what you can even see. This is because of the amount of pressure it is under, and especially amount of pressure a windshield is under when driving full speed. Which adds an incredible amount of even more pressure to it. Depending on the out side temperature, it could make is spread quicker as well.
This may not seem like a big deal, but when dealing with it in your windshield, it is a huge deal, and should be dealt with accordingly. One of the best methods to getting this fixed, is not replacing your windshield at all. Instead, you can have a liquid of some sort pushed into the rock chip itself, and this will in turn reinforce the damaged glass, and help alleviate any potential for a crack to spread across the window.
So in the end, the thing you want to look at the most when dealing with a rock chip is what is involved in the process of fixing it. This is very important when dealing with rock chips in the windshield, and very important to the safety of the passengers as well, considering what a cracked windshield could eventually do to the people inside the car. So the safety is important for your windshield to be well maintained, and the safety of the people in the car, and the people around you on the road. This is all important to consider.
