New to WSR, need advice please

[ChipdOut]

Hello All,

I have been doing repairs for over 8 months now... i still have trouble with some that won't fill, why? Am i not drilling enough? for example i did a repair today and the crack had a bulge in it right at the center of the pit. I drilled & cleaned the area then placed the injector over it and did 3 cycles of 5 min pressure and 30sec vacuum. Still the crack looked like it never filled. so i went inside and flexed... still nothing. I looked at the crack from a diff angle and it looked filled but if you look at it straight you can still see the black. Could the crack be filled and look like its not cuz of the reflection of the laminate film?

Black is air, if you can see it is still there. Please let us have some more information about yourself, your equipment, your training etc. This will assist us in giving you a more informed answer. I would say by your question we could do with starting right back at basics.

Questions like did you dry out? did you use a UV shield? what type exactly of break it was? do you think it might have been attempted before and so on.

Give us some more clues and we will all give what help we can.

Hello ChipdOut, welcome to the forum. Drilling is nine out of ten times NOT needed. Your question (Am I not drilling enough?) is not all that clear to me, did you mean the depth? Or just drilling in general? Anyway, also your pressure (5 minutes) and vacuum cycles (only 30 seconds) make no sense to me. The other way around, yes, that would maybe make some sense. What system are you using? And did you get a training? And with crack, do you mean a long crack, or just a damage like a star or bulls' eye? If it was a long crack, was it surface or sub-surface? BTW; If it was a (sub-surface) long crack, no vacuum cycle would be needed. Sorry for all the questions.

ChipdOut,
I’d like to welcome you to the windshield repair forum. The search feature is a great place to start for valuable information and proven solutions. If you are using Delta Kits equipment, I would encourage you to call into Delta Kits at your earliest convenience so one of our certified technicians can walk you through a repair.

Welcome Chipout,

When it comes to doing a crack one thing to take in consideration did the owner clean the windsheild with rain-X or in the windshield wiper fluid if so that will make it look as if the repair wasn't done. Also humidity in the air can effect repairs. What I do is clean the pit out inject with a syringe acetone dry it with a handheld evaporator and that should help a little.

hello welcome to the forum,

Ive had a few chips over the years that have baffled me as well. It usually come's down to how much resin was being used. Sometime you have to burp your bridge and try more resin and use you pressure and vac cycles the right way (VERY IMPORTANT) also make sure you use your uv screen every time (ALSO VERY IMPORTANT) good luck hope this helps.

Thanks everyone for your help, but to answer a few questions i am using the B300 Delta bridge which came with the kit i bought. As for training i worked for a small mom & pop WSR buiness locally that showed me a few things and put me to work asap. I just recently started my own deal with repairs and is planning on going out to get some real training at the Eugene office soon as i can save some $$$. Now with my issue... the "crack" refered too is actually a chip with 2 dark legs. I actually stopped to spoke to another WSR guy and explained to him my problem. He told me the same thing Jbrodie said "If the owner clean the windsheild with rain-X or in the windshield wiper fluid if so that will make it look as if the repair wasn't done".

I suppose by burp your bridge you mean remove it? Are you using a system that requires front loading?

Since you are using Delta Kits equipment I hope you will give us a call as Korey suggested, and Ignore Frank EU's advice about the pressure and vacuum cycles. It sounds like you are doing that part properly. Sorry Frank, but different systems require different procedures. I'm not sure what is meant by applying Rain-X making it look as if it were not repaired. That has not been my experience and I don't think that is the problem now that we know what equipment you are using.

I have too many questions and possible solutions to list here as I have a very busy schedule today, but it could be that some of the cracks are on the inside layer of glass, that you had contamination in the break (unlikely), or simply that you did not get it filled properly. There could be a number of reasons for this, but it's not because you are not drilling enough, or a reflection from the laminate. It also does not matter if the cracks are surface or subsurface. Again, I can say these things with confidence since we now know what you are using and therefore what the equipment's capabilities are.

Give us a call and try our suggestions, then you can post your results after applying our advice.

Gotta run for now.
