Windshield Repair Forum

Howdy folks! I had an interesting experience about 2 weeks ago while repairing a windshield on an RV. Everthing was basically going great! got the air out, injected the resin, but when I went inside RV to see how everything was I noticed not much had changed! it was as if I had injected water in the crack! I have been doing windshield repair for over 19 years and have not had this happen before! Can anyone tell me why this might have happened? Thanks in advance for all your responses.
Have a Blessed Day!

Totally confused as to what you mean, sorry about that. Water has a slightly different but barely noticeable refraction index when compared with glass and of resin, I must add that uncured resin has I think a refraction index about the same as water, so I do not know what you might have been seeing. A picture tells a thousand stories, so that would have helped.

What I met by my statement "Flowing like water" was that it appeared that nothing happened when I injected the resin into the chip. I understand the differences of when water is in a chip however, I was using the word "water" as an anology. So, even though I got the air out the "chip" it looked the same as before I filled it. I know the chip was filled however, by it looking the way it did just did not appear right. I am sorry to say I did not take a picture. Should this problem arise again I will. Oh and when I used my pit filler on it same reaction, "you" could still see where I drilled. Again, I have not had this happen to me in my years of doing windshield repair so I am a bit flabbergasted to say the least!

You and me both, best to put it behind us and get on.

Have fun.

Could the problem have been that the break had been repaired before? I have run into this situation before when a customer would come in the shop wanting a chip repaired, I would examine the break then I would see another break on the windshield and point it out to the customer only to be informed that it had already been repaired. Looking at the chip it did not appear to be repaired at all, however upon a closer inspection you could see where resin was injected only in body of the chip, in fact not much resin at all. If that were the situation in your case then even if you drilled into the middle of the chip, if it had been injected with resin by someone else this could possibly prevent any of your resin from filling the break.

I am with you screenman!No sense but it probably was an old repair!
