Windshield Repair Forum

From where I am sitting it looks like both pieces of glass are damaged, a big no go in my opinion. I have produced the same style damage using the same tool often. If the damage was just in the outside glass and not in the acute area then I would say those legs would fill nicely with a little flexing.

Firstly, may I congratulate BFW on the quality & labelling of his images. Can such kind of break be repaired?, definitely not in the drivers prime vision area, but If this was a real job I would take it on as a challenge having firstly agreed with the customer that this is a " nothing to loose" situation. Once reaching the point where the resin is not flowing any further into a leg, I would then gently pressure the glass from the inside of the windshield, using a finger or thumb and applying a pulsing pressure, close to the end of the leg, watching all the time for resin flow. getting the applied pressure just right is the trick and it takes a bit of practise.

I got this break repaired. I forgot to mention it is just a brand-new windshield I bought for practice. I tried to use this rubber ring bullseye maker to make a bullseye on the outside layer of glass, but mostly it just appear a break like this. I checked this break, it seems a break on the inside layer of glass(can only check the loose glass inside) although I impacted from outside layer. I reversed the windshield and practised to repair it.

I'd like to show pic. before and after:

After the repair--front view:


After the repair--side view:


I performed six pressure and six vacuum cycle to do the repair, every pressure about 3 minutes and every vucuum 30 seconds.
Its shows that most of the tight legs(subsurface cracks that emanate from the break) still exist, is there any other ws repair kits can fill such tight legs?

Assuming it's a break on the outer layer of the windshied, can such a repair be accepted by the customer and the insurance company?

Would you please let me know how to repair such tight legs? Any technique or any kits can do it?

I didn't press on the other side of the glass in this repair, I will try this method later.

Thanks everyone who participate in this topic, it is really very helpful to my practice. It's a great forum to learn the business and share. Thanks Delta kits runs it to improve the ws repair for all customers in the world.

Would it be possible for you to take a picture flexing the legs from the outside of the glass, then one flexing from the inside.

It looks to me like you got the resin to flow partially into the cracks, so there is no reason you should not have been able to get it to flow all the way to the ends of the cracks in my opinion. It also appears that in some of the cracks you were able to get the resin to flow all the way to the end, or nearly so, but there is air trapped in the middle. Were those with trapped air surface cracks or sub-surface cracks? Flexing a surface crack during the filling process can sometimes introduce air back into the crack.

BrightFast,

I'm a little confused. When you stated you reversed the shield to repair did that mean the inner layer was damaged? Before you stated lines where filling from outside but only so far. Did the damage you created cause damage to both layers and you repaired them separately. Just curious.

sorry for the confusion.I tried to use this rubber ring bullseye maker to make a bullseye on the outside layer of glass, I use it to impact on the outer layer of the glass. Occasionally it can make a bullseye on outside layer, sometime it make a break on the inside layer of glass although I impact from outside, this break is. I repaired the inside layer, but this repaired photo is taken from outside. Sometime this bullseye make break the glass both inside and outside. Thank you.

A rubber band pulled through a 10, 11, or 12mm nut works well.

Really good idea if it works，Thank for sharing

Sunshine wr,do you have any idea to replace drystar to get rid of moisture in the break?

BrightFast,

Not to criticize but rather to inform. On practice shields you'll first have to create the right damage and then repair it. Causing damage to 2nd layer and trying to repair it won't help you. Yes, you can flip it over and repair from the inside on a practice shield but you wouldn't be able to accomplish that with a fixed piece in a vehicle.

Spend the money and order the right tools for creating damage that will help you learn. Whether it be Delta or somebody else.

I personally have a collection of self made damage making tools but that's only because they weren't available when I started. Today they are so why not use them? As far as to your drystar comment to sunshine...you need to have one of these in your tool box if you seriously want to provide quality repairs year round.
