Crack Resin ??

[Repair1]

Been having a few cracks fail, they looked awesome when they were done a couple months gone bye now a couple have failed.

Has to be resin I would think? What

[gt_repair]

I use nothing but Glass Technology CR resin. It verry seldom fails me.. Depending on the age of the crack, and I advise the cust. about the failer that may acure.
Give them a try if Delta Does not mind.

Good question. I wish I could help, but I seldom do any cracks. I did get a call today about a 6" crack. That's weird.

It seems like just about every suppliers's crack resin has had both great and poor reviews on forums like this. You take the same resin, and some guys swear by it and others say it didn't work for them, or brand X is better. Who are you to believe?

Besides, as you know it may take months, or more... to really find out if it is "working" or what the success rate is. I would like to see the guys who repair a lot of cracks call all the customers a year later and see what's up. That would be some valuable info. That's what it would take to sell me on selling crack repair.

Right now, I don't even do cracks for the dealers. But that has more to do with most cracks being too contaminated... they are not "fresh".

I did a test a couple years ago on a practice windshield with some different resins. They all still look good, but that's just a windshield in my basement. That test didn't do much. I think I need to bust a crack in my wife's van, and get a real world test. he he

IF there was a magic resin that could hold and look great for a couple years 90% of the time, I would be on crack a lot more.

Why don't you just buy some GT resin and try it agin before you start downing cracks. Yo some like a replacement shop that things that repairs are a scam...
You sound negitive to cracks. Maybe you could make a little more doing short cracks and as your faith in the resin and your self gains you can go longer..

The GT resin Flexes with the glass to allow flexability instead of getting totaly hard.

Give them a call and they can tell you more.

After 7 years repairing all kinds of damage..I have found that Janvil crack resin works best for me. I just finished repairing a previous clients windshield and examined a 6" crack that was about 2 years old and it looked GREAT! I was reminded by the client that I repaired this crack and that she was very happy that it didn't crack out. Janvil works for me on cracks.

You're joking, right?

I have been repairing cracks for a long time, I agree with GT repair about Glass tech CR resin it seems to work good. Others fill good but dont seems to seal and last.

Why don't call you competitors and and ask them!

NOT all resins are the same. Just like paint's, car polish, shampoo, ect.

If everything was the same then we would not have a choice, we all would have to settle for the same, just having differant suppliers.

I don't intend this to be in a bad way but don't be blind to what others do with there products.

Glass expandes and contracts. Right? The resin alows this to happen. (flexible)

I even have a sample of the CR resin that have dried from 4 years ago that I use to show my customers how flexible it is. And I explain that ther W/S expainds and contracts with the temp.

Does yours do that?

Easy, gtrepair. I didn't mean to sound all negative about cracks. True, I don't focus on cracks, but do them, and I've been a repair-only guy for over a decade. I thought I was being balanced and reasonable about the issue. It's a good issue to discuss... hopefully a lot of guys will give their thoughts. I hope to learn something, perhaps brush up on crack do's and don'ts, etc.

I believe that most guys doing cracks don't actually know what they look like down the road. Granted, the same is true for chip repairs too. But, you don't hear about failed chip repairs from experienced wsr techs like you do about cracks, so it seems to be an issue. A crack repair that "looks awesome" should not be failing in a matter of weeks.

I didn't say that there is no good crack resin, but simply that you can pick any brand, and find guys who love it... and usually others who don't like it. Obviously, "user error" or poor conditions may be the reason of some negative reviews. I can think of a brand X that has been praised by some, and absolutely trashed by others. The magic resin comment was just referring to a utopian "perfect" resin that looks perfect and never fails, ever... on any crack length or type.

I think I have good crack resin, and have no reason to doubt it. But I don't do a lot of cracks, and I haven't "tracked" the ones I have done to see how well they hold up after a year or two.

One reason I don't do many cracks is because I do dealers, so I don't know how old they are. Even when they look nice and clean, you dont' know for sure until you do it. It's a crap shoot... will it be clean or dirty? I have done too many that ended up having some crap in the bottom... $0 charge. I just got to where I don't even look for the "good candidate" ones. Maybe I'll have to break that habit...

But I have found it interesting to hear the experience of other guys. I like to hear about actual documented long term repairs. (Same goes for pit resin, btw.) Sherm and Gt's posts are good examples. I wouldn't mind getting some GT crack resin... maybe it's the magic resin. I may actually crack the w/s on one of my vehicles and experiment with different brands. No kidding...

Do most of you agree that it's a fact that crack repairs have a lower success rate than repairs?

like you were saying, it depends on the condition and how old the crack is...
You can look at a crack and can tell pritty much if it is old or not by looking for little dark specks at the impact or on the edge were it started.

I will explain to the cust. on what I think and see, then tell them what I thonk it may look like and the % of holding in that area.

I tell the cust. when done that if they see ANY thing open or move past the end to call right away. I do keep a close eye on most of my work being that most are repete work and as of now doing cracks for 8 years I think I only had 4 call backs..


GT has changed there CR resin about 8 years ago (guessing) And I can say the CR they had back then before this CR I would not use or trust to hold. This CR is pretty. This last summer they sent me a batch over to try knowing I do a lot of cracks and dolong ones. They told me to try it and tell them what I thought................ I did three cracks at N/C and let the cust. know I was using them as ginnie piggs knowing they were thinking of replacing it anyway.. I did the3 and they looked GREAT the first day but had no strength on the follow up in 2 days. I called GT and gave them my thought going on nothing and they said that is what the thought.

That is what I like about GT, they go by what most of us think. If it was not for us using there product they would not be in business.

I have tested for them in the past on the CR and they were seeing if this was up to sniff. Not this time..

Sorry if I sounded harsh to you glass doctor, I have been told that way to much.

Staight to the point. don't beat around the bush..
