Windshield Repair Forum

GT_Repair,

I thought you were joking about the "resin flexing with the glass" thing so I wanted to make sure.

You can put anything in the break, and it will expand and contract, including our resins, including GT resins. If you fill a bullseye with water, IT will even expand and contract "along with the glass." That certainly doesn't mean that water will stop a crack from cracking out!

I just thought you were joking about someone using that as a marketing strategy.

I fix a fair amount of cracks,however I would rather not simply due to the fact that I can fix many breaks in the same time as it takes to fix a crack. I have had extremely good luck with using Janvil Crack Erase and also Glas Weld Crack 2000. If a crack is over 2 weeks old I will not touch it. I did do one using the snake oil that is talked about on this forum from way back and it DID fail. I have access to 3 cracks that I fixed from 2-3 years ago and still looking fine. I always drill and pop a mini bullseye at the end of the crack to anchor it. I tend to take extra time in my curing times also.I am sure there are plenty of good resins out there other than the two I use. I really feel if the crack is or looks contaminated it it best to leave it alone. Also I ask if they use any rain treatment such as RainX and if they do I pass.

Great advice. We definitely recommend popping bullseyes at the end of cracks, regardless of what resin or system you use.

I think GlasWeldtech is right about passing on older cracks. I do know that some old and dirty cracks I have filled didn't fare very well. These were some experiments here and there. I don't think it has much to do with good or bad resin, but just crappy cracks.

Now I gotta go see what the snake oil is, I don't remember that one...


Oh yeah.... how "short" of a crack do you guys start popping bullseyes? I did one the other day that was a star with about a four inch runner. I anchored it with a bullseye just to be safe. It's unusual for me to find one this short, and not touching the edge of the windshield.

Oh, I think I have pics of that crack too. I will see about putting them on the net somewhere and posting a link. I have never used any pic-posting services. If you know of a good free one, let me know.

Glassdoctor,

If you email them to me, I can put them up for you.

I want to let everybody know that when I was talking about failed cracks I was not using Delta Resins in fact it was Resin from the NVS guys that have gone away now?

Also so you know these few that failed were awesome when I completed them I know it was a resin failure because it looks like nothing was every put into them, lessoned learned that

Repair1, I had a bad experience with NVS pit filler turning a bronze color, so I disposed of it. Now use Delta Kits pit filler (after testing several). I really like the viscosity. Are you still using any NVS resins? Reason I ask is, I still have over a gallon of Liquiglas UV (medium). Never had a problem yet with any chip repairs using it. Starting to think maybe I should just dispose of all my NVS chemicals, no more support available anyway. Last thing I need is good looking repairs that later fail.

Ridgerunner, definitely don't toss a gallon of resin... you might think back and see if tehre are some jobs you did a year ago that you could "check up on". Then you will know better if you ahould be concerned. Even if you don't want to use it for your "paying" jobs, it might come in handy for "playing" with new equipment or training a buddy... "practice resin".

I posted a couple pics of the "short" crack, so I will put a link here. I actually was not that happy with it. I missed a tiny spot in the center of the crack and cured it before I noticed. The rest of it was fine though. You can see in the after shot the pits of the star and drill mark at the end.... oh and the black spot in the middle.

I have been using the NVS resin on chips I do enough fleet work I see the same trucks often they all seem to be ok.

Great pictures!! Glassdoctor

Sometimes a flaw gives a better image in the customers mind just incase you have one of those I think there perfect. If it's ok with you may I copy them?
