Long Crack Repair

I use the GT system. I am not with the company.

I use the CR for the cracks. It has a good bonding strength and have not had to my knowledge a major crack out. I will use MV or LV on legs that may only be 2" or so. But if they are longer I use the CR. and average 12 - 16" long. I will go longer but then we price what a W/S would run to see what is a better deal.

I am very pleased with there resins for the fact the low acid and the cosmetics are great.
I do not use the HV that much, even when it is down right hot out. Just to slow to fill with for me..

I am one of the black sheep's here because I am not much on the Delta resins... Every one has a choice. Gt is mine.

If I was wrong how would in what way does the resin set too quick? how does it set without the UV bit I mentioned? I have no problem with your choice of resin I have said many times if it works for you that is great. I will however always write my opinions and it is up to the reader to decide if they want to take any notice of me.

I do not use my award to beat guys with I would imagine most people on recently would not even know who I am, I just write as honestly as I can and do not leave out what I feel is the main point for this I apologise to you.

In th UK most so called repairers have a saying, I can do a bullseye but have problems with a starbreak, I have never seen another repairer using any type of UV shield could this be their problem along with of course 90% would not have been shown how to dry out.

A very simple UV present test is extremely easy to carry out as I have written about before.

GT for some one who was not going to defend their post you made a good job of making me feel guilty, I am sorry if I touched a nerve.

I have a ? for GT Tech.Do you have any connection with GT.Technology out of Colorado?Just wondering because I have tried the CR resin and prefer the MV or the HV,they seem to do better for long cracks, the reason I use GT. resin is because it has less acid in them and I have a skin problem when I use other resin with a higher acid base.

Lower acid content = lower bonding strength, so I'm always surprised to hear that technicians choose a low acid resin for repairing long cracks. Delta Kits and most other companies sell "Acid Free" windshield repair resins, but recommend resins with a higher bonding strength for obvious reasons.

Our MagniBond resin is formulated to have less "acrylic" acid, but still maintains excellent bonding strength as we incorporate a different type of acid that has the benefits of acrylic acid without the toxicity. There are other ingredients in some windshield repair resins that are also quite toxic, and we stay away from all of them. Unfortunately once a person has had a reaction so some of the more toxic products on the market, they may have problems with any type of windshield repair resin. In fact, even though acid free resins are safe for just about anyone, there are people who cannot even tolerate those products.

Now before you get all bent out of shape gt_repair, please understand that I am not bashing the resin you use, and I am not attacking low acid resins. As I said, Delta Kits sells low acid and acid free resins as well. I know you feel like you are a black sheep on the windshield repair forum, but the truth is there are just as many forum members using competitor products here as there are Delta Kits users, probably more. GT and LR have been particularly well represented here, and both of those companies have very loyal followers. I disagree with many of their theories and believe Delta Kits has better products, and they feel the same about their products, but that doesn't mean I have anything against their companies or windshield repair technicians that choose to use their products. Some people like Fords and some like Chevys. Which one is better depends on who you ask.

I did one recently for the recon mgr at one of my dealerships it was his own car and didnt have insurance to cover it it ran verticle from a chip under the wiper blade up about 24 inches to just about the rear view mirror I used magnibond I placed the injector on the chip and started the crack at the top (hoping gravity would help) didnt use a crack jack just ran a beead along the crack and flexed with my thunb and slowley worked my way down to the chip placing a cure tab over the area i just did until I got all the way down. the whole process took about 30 minutes and afterwards you would be hard pressed to find the line I hadnt used magnibond for cracks prior to this and was quite suprised at how easy it flowed into the crack.I am not a big believer in doing crack repairs for retail auto customers but on the rare occasion I do one now I think I will be sticking with the magnibond

Does anyone have any shrinkage issues with the thinner viscosity resins with long crack? I'm trying to inject the thickest stuff I can depending on tempature for better strength repairs. Seem there are some different schools of thought on the viscosity issue. Any words of wisdom?

I never have a problem with the resin I use. GlassStarz, I would have started that crack from the bottom up as I prefer capillery action to help the job rather than gravity. That said we all know there is far more than one way to do this job. Hardest cracks to do in my opinion is horizontal one's, for some reason verticals are nicer. Does anyone else find the same thing and can give me a reason.
