    Automotive Expert Judy Greenway demonstrates windshield repair using the bridge method.

    Judy Greenway: Hi! I am Judy. We are back from Royal Glass and we are going to demonstrate today the bridge method of repairing a windshield. So, let's get ready. Okay, now we are ready. Now what we have here is just a standard drill with a diamond point drill bit. And what we are going do, our repair area, we have a stone chip right there, we are going to drill down through the first layer of glass.

    Now as you can see, we took the pill down through the first top layer of glass and what we are going to do know, we clean off the area. And we are going to move on to our bridge and of course, professional bridges, they need the suction cup on the bottom, make sure it's nice and moist. And we are going to gently, gently put this on top of the drill hole. Of course, it takes a little angling and a little bit of pressure. And of course, we tighten it down to the glass. And of course, light treated plastics have to be covered. So we are going to gently cover that over and hold a seal right there. Now of course, liquid plastics, a couple three drops and gently, gently we are going to force the plastic down into the break. And stop, cover it, give it a few seconds. Let it filter down. Then gently, gently back of the pressure just a little bit. Make sure the plastic is dropped down and gently reapply pressure. And of course today is a wonderful day, it's beautiful, nice and warm. Glass is nice and warm. And this what does a beautiful job, it pulls the plastic out into the break. And we are going to let that set for just a few seconds. Now if it was cold, rainy, you would want it inside. If it was overly hot, you would take, roll down your windows on a hot day. You would take a nice towel, just cover over the windshield, cool your glass, you don't want it -- you want the glass, so you could be able to touch it, not so hot of a burn, burn your fingers, you don't want that. And then we are going to cap it off and of course we just use little light pieces of plastic, so the UV light can come down through. And of course, cover, keep your face safe.

    We are going to slide the little plastic underneath the tripod. Now what we are going to -- what we have here, now of course it would be easier if we didn't have to cover it in the sunlight but UV plastics harden so quickly. And it really is basically a one shot, there is no redoing it, there is no retakes because the light starts hardening the plastic as soon as you break the seal. So this is what this little cap does here. While it's hardening, it holds pressure and it holds the resonant. So right there, right now, we will let cure for a few seconds, doesn't take long in the sunshine. And we are going to peel that piece of plastic away, cut it all cleanly, right, with the razor blade. I am going to find my little razor blade here. This is the best way. There is the little patch comes off and of course there you are. Nice and clean, a little cleaner and there you are. And we have also professional top capping, it's diamond chipped compound mixed with the liquid chemicals that we insert on the inside, makes a very nice finish, makes it nice and clean and shining like the rest of the glass. And of course this will dry, it's UV light treated also. So you just that touch that right on top, and voila! And of course, you tell the customer very carefully to no fingers, no touching. And within 15 minutes that will be hard just like a lock and will never break, spread, looks good. It's never going to be like a brand new windshield, but it will look clear, it's safe to drive with it. Well, I would like to think that these two tips that I have showed you today will help you make determination. If you want to bring it in shop professionally and have it done or use the little kits that we showed you that comes out of the auto mart store and hope to see you again.
