I'd like to address several misconceptions in the posting from ceejay 2005.<br /> <br /> 1.- Yes, the plastic laminate holds much of the windshield fragments together, but is actually a mortal danger to unsecured occupants in the car when their heads strike and pass through the windshield. It's the return stroke of the person that causes the damage.

I'd like to address several misconceptions in the posting from ceejay 2005.<br /> <br /> 1.- Yes, the plastic laminate holds much of the windshield fragments together, but is actually a mortal danger to unsecured occupants in the car when their heads strike and pass through the windshield. It's the return stroke of the person that causes the damage. You see, after passing through the glass and the plastic membrane, a person's head and neck are impaled by the dagger-like ends of the windshield shards sticking to the plastic membrane. There goes the jugular!<br /> <br /> 2.- In this respect, the Euro windshield is far superior. A head hitting an uncracked Euro windshield will shatter the tempered single-layer glass into cubic pieces and a 10-inch diameter part of the windshield in front of the driver, much of which will end up all over the driver's lap. When the reverse body-stroke occurs, there are no dagger-sharp shards aimed at the person's jugular. Where was ex-governor Christine Whitman (Federal DOT safety chair-type idiot) when she should have insisted on converting death-trap US windshields in the USA to much safer Euro windshields? By the way, the 10" diameter clear area in a Euro windshield allows a driver clear forward vision in case the windshield does not fall out of the frame after a stone impact that crazes the entire windshield. Oh, those clever Europeans!<br /> <br /> 3.- The windshield repair kits were specifically designed to fix chips or cracks within the wiper-arc on vehicles in the USA. When done properly, the final result is an INVISIBLE repair to the glass.<br /> <br /> 4.- Once started, windshield cracks will spread due to the flexing of the windshield frame as the car hits potholes and speed-bumps in the road. Air pressure over the windshield is seldom great enough to propagate cracks. Cracks can spread over the entire windshield, but will pose no additional danger to the vehicle occupants. Remember, this is in most every case just the outer glass layer that's cracking. That is in fact the single positive part of the laminated windshield design that works. Inject the crack with resin, or let it go, it SHOULD not matter from an engineering standpoint, but the states usually requires that a cracked windshield must be repaired or replaced. FOOLS!<br /> <br /> 5. - The next correction is a doozie! The resin is injected into the crack by a VACUUM placed on the crack by a small mechanical pump that comes with a repair kit The resin is squeezed from its tube and is sucked into the crack . And U-V rays from the Sun can cure the resin (since the Sun can supply these, the repair can be carried out in your driveway on a sunny day). No lamp needed!<br /> <br /> 6.- The rest of the remarks read like the scare-tactic B.S. you hear on the TV all the time about Health Care! Do this, do that or else you will be HURT! Oh man! Whip out the flag, the mom in her apron holding apple pie, the little sweet-cheeked kiddies, and play a mournful dirge while you're at it. It's all a high -powered psychology used on sleepy sheeple to support a greed-mongering windshield-replacement industry! (You greedy pigs can't just won't leave it to good, old-fashioned honesty, can you?).<br /> <br /> 7.- WINDSHIELD REPLACEMENT: The "ad" forgot to mention that many auto insurance policies now offer absolutely free windshield replacements. Check you policy first for this provision to see how long the crack has to be before the provision kicks in.<br /> <br /> Sheesh!
