Hello, my name is Mark Blocker. In this segment, we're going to cover how to fix a chipped windshield. To fix a chip in your windshield, you're going to need a windshield repair kit, and these are available from a variety of different manufacturers, in a few different styles, but basically what it's going to do, it's going to put a suctioning device on there, by use of an applicator. To fill the voided area where the chip is, it's going to try and suck out any remaining air in there, and fill that with a polymer or glue, or something that's going to harden in there, and fill that cracked surface area. That's going to prevent the window from continuing to crack, and further damage. It's also going to seal it aesthetically or visually, so that you can't see the damage as well. The process usually takes upwards of 30 minutes to apply it, and can take upwards of 24 hours, for it to cure thoroughly. A lot of the products cure using UV rays, so you're going to need a bright sunny day for it to work, in a normal amount of time. Cloudier days, days with less UV access, it's going to take longer for it to cure, and you also want to make sure your window is at a nice warm temperature, when you do it, but I'll walk you through it. Basically, what you need to do to repair the chip, is you need to make sure it gets thoroughly cleaned, both inside and out. Take a little pin, or compressed air, and pick away at the chip assembly, pick away at the chipped area itself, and make sure you get any loose glass fragments out, prior to using a repair kit, and it's just going to set up on the windshield, on the outside, with some type of suctioning or stick on device. It will hold an applicator, that allows you to pull a vacuum on it, and then simultaneously apply a pressure, that's going to fill that chipped area with a glue, or bonding agent, and that procedure may need to be redone several times, over and over again, in order to purge all the air out of it, and fill all those cracks and crevices with the sealant. The repair process could take you in excess of 30 minutes, just to apply it, and then several hours after that, to allow it to cure, so make sure that you've read the directions thoroughly, follow the instructions on the packaging, and make sure you have ample time, to properly complete, repairing the chip in your windshield.
