Keep up the amazing work I love you also first to reply

Now that you have a sturdy bench you have several experiments that you should do over that the looseness of the previous bench drastically affected the outcome.

i think you woulda had better results if you didnt use the blade like a hammer to skim off the resin. shoulda sliced through it like @ 19:14

Only scenario I'd see multiple hits like that would be large size hail

Yes, defost/heat can absolutely cause cracks to expand. It happened to my windshield from a chip chip was stable all summer so I didn't try to fix it with a kit like this. Winter came...defrost...crack stretched all the way across the windshield. Fortunately it does not obscure my vision and has been stable ever since the 1 crack formed.

Hso did i.

Glass is harder than steel.

@@Jexorz86 Hardness isn't really a huge factor once you're dealing with quick impulses and all. The glass is harder to scratch and would take more force to indent, but the actual energy needed to deform it to failure is extremely low. Something like a hammer can produce absolutely enormous momentary pressure, so they can even break diamonds with little effort. Like glass, diamond can not absorb much energy before failure, while metals can generally take huge amounts of energy.

@@markjacobson4248 This is true, but glass if very very hard, so you have to smack it alot harder than you think to actually crack it.

@@Jexorz86 glass is only 5.5 (house wares) to 7 (Corning's claim on gorilla glass) on the mohs scale. It depends on how its treated when formed). Hardness does not equal toughness.

Yep I used to do this professionally, then scrape off the thin layer of excess resin with a razor blade and it looks super clean as long as your crack isn't too big to begin with. If it is you have to replace the whole windscreen.

Did anyone expect him to understand lol

They just have a industrial vacuum that it suction itself to the windscreen instead of the adhesive strip ring

Yes, very similar idea to people who do resin casting. The vacuum helps to pull trapped air out, then pressure helps to minimize any remaining air bubbles. People who do resin casting often use things like paint pressure pots to apply vacuum and pressure.

was gonna comment this, glad I didn't need to :P

100% hands down the sylvania kit. the 3m kit doesnt come close.

2nd the Sylvania kit

Project farm did it. Tbh I use Xs Motorsport head light restore kit. They all about the same. Sand and polish

Do a headlight repair kit.

Pretty sure it is not his car, his car is a Toyota something, it is a truck. This car isn't a truck at all so it is not his car. So not his windshield at all.

Facts

crazy/super glue works to bond the crack but also "steams up" and sheds a stubborn to impossible to remove film. That's why I don't use on broken sunglasses

@@atlasgunther8947 have you ever tried clear gorilla glue? I had to repair a jewelry display case and used that as a bonding agent between sheets of glass. I was incredibly impressed at the strength and clearness for its price as it was my last resort before bringing my superior a $300 bill for glass adhesive haha

or nail polish. The gel and polish kind.

@@keithbroh5730 you know they make a clear liquid nails for glass thats like $12 and is meant for that purpose

i was gonna suggest a bb gun

This method will produce much more representative cracks and chips. Without going into too many details, glass fractures based on a pretty complex set of factors which includes previous impacts and, more critically the velocity of impact. The low velocity, high mass hammer blows will produce generally smaller chips with a larger potential for spreading cracks, where the elastic impactor method uses a higher velocity, lower mass impact which will be more likely to produce larger chips, chips with spider webs and, on the very high velocity end, chips surrounded by concentric rings and spider webs. I had been about to suggest something like a BB gun to produce higher velocity impacts, but this elastic impactor system sounds more reproducible and much safer. I suppose if you need particularly high velocity impacts, you’d have to use a smaller mass and either pull further or use more elastic. In any case, the test would also be somewhat more controlled if each product were tested on a different piece of glass, since every impact, even if it doesn’t produce visible cracks can still cause microfractures that weaken the pane.

@@Rms2015you sound smart but the thing is using an elastic band on your finger will never give you consistent results as each time u fling it will be different strength/stretch on the elastic band BB gun would be better as that would be consistent

@@nickjeffrey8050 I hear you, but I never said the impactor should be cocked by hand. While it is true that elastomers decay slowly over time, eventually leading to less powerful impacts, this effect is small enough to be irrelevant to the test and can be remedied by simply replacing the elastic at regular intervals. While at first glance, it would seem that a bb gun would produce more consistent results than elastic impactors, the reality is that regulating a pneumatic gun to precisely the right pressure is much more difficult than replacing elastic at regular intervals. If you run the pneumatic system at perhaps as high as a few dozen atmospheres, you can get the control fairly precise, but due to the inherent limitation of pneumatically actuated projectile launchers where the velocity of the projectile cannot exceed the speed of sound in the working fluid, which itself is partly dependant on pressure, such pneumatic guns have to be run at hundreds of atmospheres, at which pressures regulation stops being precise. Add to that the safety factor of having an unsecured bb flying around at high velocity and contrast that with the elastic system which is far simpler and tethers the impactor, reducing safety concerns, and I am no longer convinced that the pneumatic system makes any sense. At least not until you need extremely high impact velocities, at which point it might be time to consider coilguns instead

Could you do video to show that method please!

Yea the old heads always say hit it with a lighter lol..they tell techs now not to do it haha..me personally I'd rather do the full install lol

I just take my car to a windshield repair place

@@jaskajokunen3716 I used to do windshield repair, did it for 20 years

The only thing a lighter will do is help remove any moisture in the break. Heating the glass will cause it to contract and create a false appearance like its filled in. But once its cools the glass will expand and go back the way it was. Which system do you use? And where did you get your training?

You can't go by this anyway. He didn't follow the directions properly on any of them and the last one the crack is under the lamination so the resin couldn't get into the crack anyway. He let them cure way too long before removing the excess. That's why they all leave white spots. It's not supposed to be fully cured when you scrape it.

​@@erzebet6977What, do you not drive your car around at all? the UV resin will continue to cure after the recommended time and will whiten like his test.

@@inferno7181 not if you scrape it off before it cures fully like you're supposed to do

brake fluid and a scrub daddy... you can thank me later...

I can say this because these are virtually the same. At one time, I had an 05 Ford Taurus and my younger Brother upped me and got a 03 Mercury Sable. I ended up replacing the headlight assemblies and keeping the bulbs. On the Sable, I tried various headlight cleaners, but since my brother was in college and VERY cheap, I sanded the headlights back to a dull yellow and he got halogen upgrade bulbs. Getting the halogen bulbs was cheaper than the headlight assemblies. We don't own either car now.

Ive done a turtle wax kit and they worked really good. Really easy to do as well

ProjectFarm. I used the Sylvania from his video and it worked and maintained its results.

@@aroundtheclock1587 well clearly that's not true as my comment is right above ⬆️ thanks for your pointless comment though

@@OMW2FY-B u don't go around just saying it that's called attention seeking if u have depression get help rather then telling people it's not pointless ur using a real condition like depression as a way to grab someone's eye

@@aroundtheclock1587 who hurt you?

I'm surprised he didn't just pull out a bb gun and take a few shots at it. Those are usually pretty good at leaving decent chips.

Smart!

It doesn't say anything about zuckanee on the packaging though

This is what I was looking for in the comments, the winters here in MN will kill a windshield with a crack. I was warming one of the F150s at Ripley before driving out hot lunch in the field, not knowing that the mix of heat and cold would cause the chip to quickly spread into a full side to side break with 3 branches

Same

You don’t know that, the video hasn’t even ended for you yet

You were correct!

@@brighamruud5090 I was about to say he says it the first 10 second 😂😂

I mean, he has a truck and stuff pretty sure.

@@skylerblack6017 Lmao

Noticed the same thing the other day, think its a heat crack it starts from under the window trim not a chip.

I am in need such a product as well

Plot twist Tyler caused it

All of those tire repair kits that inject goop into the tire to seal it are horrible. It will require a ton of labor to remove from the rim later. Absolutely not worth the trouble.

They did that on Garage 54

Great idea.

I would also enjoy that

I wonder what kinda company dont know how to replace windshield with sensors on it :D Most windshields have sensors, cameras, heating etc these days...

I live in the uk and most car insurance companies have contracts with wind shield repair guys to do it for free. The explanation over the phone was brutally honest; it's basically cheaper to have these guys go around and fix chipped wind-shields than it is to pay for accidents with chipped wind-shields as the root cause.

You bet wrong.

@@maplecitydistributors5493 got a better explanation?

@@pauloday5198 I'm still sitting here trying to figure out how after watching this video, that is the comment you came up with.

You are on the money. You have clean out the chip completely - even drill it out and then apply. Then you will only see a light discoloring, but it is clear.

That's what I was thinking the entire time. On the other hand, I liked the way he did it because he followed the instructions exactly. And the instructions didn't tell him to do that . It should be something that they include

I didn't know mobile data limits existed still in 2022. Are you in the US?
