Is Cyanoacrylate Used For Windshield Crack Repair

Am looking for advice on drilling drinking glass. I have a scissure in the windshield of almost a foot from the right upper portion extending downwards. Information technology is only on the outer portion of the sandwich. I was considering drilling a small hole just at the end of the crack. I bought a set of diamond $.25 but am leary of starting, Since it is safety glass it is unlikely that the unabridged windshield could crumble/ disintegrate. Since I have never drilled drinking glass before I am curious as to how it may get. I have gone to a site that describes how easy it is with the proper advice and warnings. I also went to a local glass repair shop and said he wouldn"t touch a auto windshield. ( he probably had some liability issues ) He also warned me "non to touch on it, equally I'll screw the whole affair up" He did not obviously realize it was already screwed up. I am of course only interested in containing the crack from growing. If everyone has any personal real experience with drilling glass I would be most interested. Please, no opinions or communication, only real experience! Thanks much. :cheer2:
I had a NOVUS repair guy do 2 windhsields for me and they came out very skilful, but they were on older cars.
Thanks for the tip, no Novus dealer in this area. I ended up drilling the hole myself and was amazed just how unproblematic it was. Now I take to look and see if the crack stops growing.
Aren't you going to shoot the resin in thehole and let it cure under an ultraviolet light?
Delight tell me about the whole procedure.

To practice it properly you need to evacuate the air from the hole then inject UV curing super glue. It is difficult if the scissure extends beyond the seal of the screen. If yous don't evacuate it first then at that place volition exist a chimera at the bottom of the hole and the glue volition not be sucked into the crack.
Given that you take made a pretty good job of stopping the crack (probably) then I would just super glue it then use a scalpel to remove the excess and smoothen it. It aint going to be perfect but it should work.

All kinds of things are possible but the more you lot mess the more risk you run of trashing the thing.
I definitely agree with your concluding paragraph. I did seal it with superglue ( the ii holes ), the initial bullet,and the newly drilled hole. Thankyou for the answer.
Unfortunately, no real experience doing this affair, other than on products and glass other than motorcar drinking glass.
Drill-stopping the cleft hopefully eliminated the spread of the crack, simply since y'all oasis't gone all the style through the glass, in that location are going to be some "funny" stress points hither and there. You may wind up with a lower or intermediate layer starting to fissure and spread from the drill end, or somewhere else along the existing crack.

If you didn't run something like acetone or lacquer thinner in the crack to clean it - y'all might have bug. Acetone cleans, but more chiefly, disperses and dries up whatever h2o that might be in the crack. Water is your real enemy here, as freeze/thaw action volition cause issues (peradventure not and so much in Sacremento, simply other places could exist a real problem).

The superglue probably won't last for long. Cyanoacrylate glues have extremely low shearing strength, so I'd expect this to flake off with the flexing and stress that occurs for the windshield. Also, the general run-of-the-mill cyanoacrylate glues are non recommended for glass, there's special varieties for use with glass (not sure, in that location may be other formulations for tempered vs. untempered glass as well).

Since you didn't evacuate/purge the air, there's probably still some air trapped in/under the mucilage. Variations in atmospheric force per unit area may requite yous some trouble in as well causing the glue to flake off. In other words, don't drive up and down the Sierra Nevadas oftentimes. I don't know that normal weather barometric pressure will be plenty to cause a problem, merely ....

Honestly, the glues the autoglass guys use is much meliorate suited, and they accept the other equipment to evacuate most of the air to assistance in the glue actually getting into the crack/fleck and bonding with the drinking glass. They aren't perfect either, and if not done correctly tin can still popular out, but mostly much better suited for this blazon of work.
Tundrwd, Thanks much for all the tips. The main reason I tackled the job was that no repair store would even approach a crack of 12" or more. My windshield crack is 15". The meridian glass seems totally flat/ level with the under glass. Afterward when it warms up I'll endeavour to use some of your suggestions. If worse comes to worse I can always take it replaced for well-nigh $250.00. Dealer wants over a grand. Have not been over the Sierra since the crack grew, proficient affair maybe. Andy

There are "windshield repair" kits that basically give yous a
tube of cyanoacrylate, a syringe, and a suction cup. The idea
is that you clean the area around the hole or flake, attach the
suction cup over it with agglutinative to totally seal the edge, and
load the syringe with the glue. Adhere syringe to suction loving cup
and pull *up* to evacuate the air, letting it bubble through
the cyanoacrylate. Hold that way for a couple of minutes,
presumably to allow any remaining h2o vapor eddy off or whatever,
and so slowly release and then push, shoving the gum in to
replace the vacuum.
.
Or something similar that. It's been years since I did this to
stop a lilliputian "star chip" in a previous automobile'southward windshield from
spreading. I caught information technology pretty early, and the set up did seem to
fill up the void and stabilize everything well.

Yep, something like that may work, if using the right glue, but from what the OP said, the crack is Manner also large for any self-repair kit I remember seeing. Probably why no 1 would touch it. Simply too large for their equipment to try a repair.
