Interior layer damage.

[Nomad]

Haven't fixed any on the inside for a long time, but have done so on occasion. Sometimes rock hits and there is no break on outside at all but there is a crack generated on the inside. Then it all depends on where it is.
Had a bulleye one time on the inside. Found out the car had been in a tornado and the back glass had blown out and a rock or something had damaged the inside.
A lot of times the damage is above the dash in a very tight area that you can't get to with your injector so can't be fixed even if you wanted to. And there are times when someone wants you to just stop something until they get home to another state.
This is why I don't like hard and fast rules about what can be repaired, there can always be exceptions.

Someone please tell me how the basic principles of windshield repair have changed dramaticly in the last 30 years? Other than better bridges, better resins and better injectors, how has the process changed in a way that was technologically advanced? When the big cutting edge announcement comes that turns windshield repair upside down, I hope I'm still alive to hear about it!
But for now, it's a process that a monkey could be taught to do. It's not rocket science.

I only wish I could find some monkey's to train in repair while my only cost would be feeding bananas to them daily!

Splitpit, your right. Doing repairs isn't a rocket science but to be truthfull not many new tech's master repair in a short period of time as I also doubt you have done.

So what is your point?

Also, please fill out your profile, it would be nice to know who you are and where your from.

Splitpit has been requested a few times by different techs already to fill out his profile, but for some unknown reason he prefers to keep a low profile.
Like I mentioned befor , if someone harresses me on this forum, I won't come to look him up and pull my 45 on him , I promess !
IOW don't you worry Splitpit !

That being said....I have to disagree. When both layers of glass are damaged the structural integrity of the windhsield is much more compromised than when it is just outer layer damage. It is foolish to think it's not and in my opinion it's foolish to try to repair interior damage. If you are doing it on your own vehicle that is one thing but if you are doing it for a paying customer I think it's wrong. A steel weld bonds steel to steel with steel. A windshield repair is far from being an equal comparison. I also don't think you will see much "revaltion" in the future of windshield repair. Equipment, resins and tecniques can't improve much more than they already have so I don't see much change in the future. Windshield repair techs. have to use common sense when it comes to what type of damages they are willing to try to fix.

Gotta luv ya Starquest, I tell my customers the same thing all the time "soon as we can get the monkeys to get the air out we'll be in competition with barnum and bailey" LOL. Who cares ? It is air out and resin in, THAT is the solution!:eusa_clap

In need of few incompetent WSR technicians to be trained to work an organ grinder near the JACKASS pasture since we have lost all our smart monkeys to WSR.

Free room and board, great travel opportunities and great tips!

My point is, windshield repair is not that difficult and the tecniques for doing a quality repair are not that hard to master. I'm not calling anyone a monkey, I'm saying that it's not some technically difficult process and that a monkey could probably be trained to do it.

As for filling out my profile, what's your point? I'm a circus carnival worker from Katmandu!

man you guys are touchy! I wasn't trying to insult anyone, just saying that it's not rocket science!

[splitpit]

And I'd still like for someone to explain the technological advances in the reapir process that have taken place over the last 30 years.

I'm not advocating either way, but personally don't feel confortable repairing glass with damage on both sides.

Reason: Like welding steel, too many factors play a role in the tensil strength of the bond that is created. While welding gives you much more control over this bond, glass to resin bond takes the techicians ability to do a repair out of the equation. What is important in any repair process whether it be steel or glass is the penetration of the bonding material to the glass or steel. In most cases we can not physically clean the glass we are bonding to. Just because a repaired crack or chip is filled and bonds to the glass, Doesn't mean that it is a strong bond every time. How can we be assured that bond will hold up under stressed conditions? What is the strenght of that bond?

Let's use a rear view mirror as an example. You can glue the bracket to the glass and use your fingers to test the bond and it seems strong, but sometimes when you put the mirror on the bracket it pulls the mirror bracket off the glass. Usually this is because the glass wasn't cleaned properly or maybe the age of the glue or the temp at the time it was installed. Regardless, with all the right conditions that bond will be strong enough to hold that mirror.

My point is, I guess, is the technician doesn't have full control over the conditions necessary to ensure a perfect bond. This isn't an issue if you have the strength of the second layer of undamaged glass.

But what about damage that is only on the inside? I have run into this once in a while. If it's damaged on both sides from the same rock it's usually too far gone to do anything about except replace. But once in a while you get weird things happening and the damage is only on the inside.
Once had a car with a big star near top and on the inside. I didn't fix it but the gal who owned it took an ice cube when the glass was hot and led one of the outside legs all the way around the damage so it wasn't going anywhere, as far as I could tell. Pretty smart! I've never tried this but always wondered if there were methods where you could lead a crack to the edge to dead end it or do what this gal did?
