Windshield Repair Forum

RV glass is really thick and if you want to flex it you sometimes have to use a lot of pressure. Sounds like too thick of resin and maybe you ran out. One time a few years back I got talking to a guy while doing the repair and forgot to put resin in the injector. Worked for at least 10 to 15 minutes, frustrated as heck cause the "resin wouldn't go in". Only time I did that but it taught me a lesson. If you didn't have any residual resin when the injector was removed you probably needed more.

Thanks so much and I have to agree with you, it will never happen again. This post has helped me so much.

abcinabq - you've had plenty of good advice in these posts to help you in the future, you mentioned the temperature at the time of repair was very hot, did you make sure the glass surface was cooled down to the ideal working temperature range for glass repair? - i.e. 13 - 25C ( 55 - 77F). This factor is even more important in thick ( commercial) glass because the equipment has to work harder and longer to obtain good absorbtion and the volume of resin required is higher. The cooler you can get the glass, the greater the fissures will open up to allow the resin an easy flow. Hope this also helps.

Yep, no dought I used the wrong weight resin...I read from manufactorer that HV was never ment for stars. Too bad, I hope the damage I used it on stays put, they were out of towners. I think I will call them and see if there is any problems and offer a refund if they want. In fact I did offer the repair for nothing, and they insisted.
