Picture of How To Repair Your Windshield
If you have a chip on your windshield, it is necessary that you get it repaired as soon as possible. A small chip on your windshield can turn into a big problem quickly. After the first layer of your windshield is penetrated, it is likely to crack out causing further damage, plus the need for a costly replacement.

Repairing your windshield when you notice a chip will save you money in the long run. You can call a windshield repair company, or do it yourself. They do sell inexpensive windshield repair kits at your local auto parts store, but if you are not comfortable with the process, call a professional.

Step 1: Windshield Repair Tools & Supplies

Picture of Windshield Repair Tools & Supplies
You can purchase a windshield repair kit from your local auto parts store, which will include all the necessary tools and supplies. I will be using a professional grade windshield repair kit, but the concept is the same.

You will need
A Mirror to place on the inside of the windshield
A Bridge & injector
Windshield repair resin
Windshield pit filler
Plastic curing tab
Razor blades
A dremel tool with special glass bit for cracks

Step 2: Beginning The Repair

The first step is to prep the chip and windshield for repair. i recommend using an alcohol pad to clean the area, and gently scribe out any loose glass from the "impact point".

Next, hook your mirror up on the inside of the windshield, centered on the chip you are going to be repairing. This will allow you to keep an eye on the chip from all angles, which is very helpful with all windshield repairs.

Step 3: Make a Seal Over The Chip

You want to center your bridge or whatever tool you are using directly on the chip. You basically want to create a seal over the area of the chip that is missing glass.

Step 4: Drop Resin

After you effectively have created a seal around the chip, put 3-8 drops of resin into the injector area.

The injector is kinda not the best. I prefer the ones with it on either side of the chip for even pressure. Where i use to work we did this all the time. The fun part was getting it drilled out right and not hit the other side. So long someone is paient and has a sharp bit it causes no problems. If you can do this within a garage do it. A UV light is also helpful to cure it if it is indoors or out doors. Cures it nice and fast without having to depend if the sun is out.

Great stuff! But I have to say DIY windshield repair is a great idea if you know what you’re doing to be honest and you can surely save some cash out of it. However it would be a great idea as well to get a professional help when it comes on this just to make sure you'll not ending up replacing the whole windshield as to the result of the DIY method you have…

Yeah, DIY is nice. But it is always better to get a professional. Just to be sure. You could make terrible mistakes.
And look, because I am giving out such unique and altrusitic advice, why not click on this link and buy 'professionally' overpriced carglass repair sets anyway.

Great information, thanks! I'm off to find a repair kit.

(Not sure if you were aware, the Austin information link doesn't work.)

@ecramer I don't see any way someone would mess up there windshield worse then the chip in the first place. Maybe too much sealer but the cn be taken off. Also no one will ever learn how to do anything without trying it first.
