Thin resin

[Delta Kits]

You can use only one resin with there system as well (anyone's injector for that matter) but they prefer to sell resins that are not multipurpose. but application specific.

Some people prefer the simplicity of 1 resin for everything(the adjustable wrench) while others prefer having the choice of more application specific resins(a complete set of wrenches).

I'm sure that the label of "multipurpose" but not "application specific" wasn't meant to infer that our resin was inferior to "application specific" resin. Since it came across that way to me, I figured I would clear the air.

Our resin is "application specific." The application is filling windshield repair breaks with resin that does not yellow, does not shrink, flows very well, looks very clear, and holds up for the life of the vehicle. It is used for star breaks, bullseyes, combo breaks, and long cracks.

Saying "application specific" simply means it has drawbacks. Our resin was formulated to not have these drawbacks, simple as that.

Argue if you want, but the results speak for themselves.

Jeff, excuse me if it came out in that way after translation in my head. it was not meant in any way to degrade, or belittle anyone. Premium Bond and Magnibond are great resins that fufill there purpose without comprimise. As you said the results speak for themselves, and in my opinion, no one is right or wrong in this debate(are you a Ford, Chevy, or Dodge person? in the end it makes no difference) we all have different ways of accomplishing the same task, which is a durable repair that satisfies the customer.

Are there any resins out there that bond to the windshield's inner PVB layer better than most?

Yvan, point taken on the # of resins. I was under the impression that some had as many as 7. 4 really isn't that many more ... (1), than the 3 I was talking about. I was actually confused until you made the wrench anology.
Thanks for breaking it down so I could understand it.

However ... for what it's worth, I'd take the two resin system and the full set of wrenches. The adjustable slips on me too much.

JT. Another thing to remember is you don't want the resin to be so thin it bolts to the end of the crack. You want it to go slow.
If you were to look at a crack on microscopic level it actually has tiny pits and valleys along it. You want the resin to slowly move towards the end of the crack, while at the same time filling in these tiny valleys. If the resin goes too fast it won't perform this very important bonding/filling process.
This is why on regular stars I don't use thin. I want those valley's to fill and I want the more flexible resin in the cracks.
Good luck. Like the rest of life, w/s repair is a journey and not a sprint.
The more you learn the more you find you really don't know it all.
Like Yvan says: different things for different people. Some like the Chevy's and some like the adjustables...... or something like that. : )

I would like to add to Boyd's wise words on cracks(or wise crack wordsLOL). In order to provide a complete fill you can modify your system to make a base for you injector to slide along the crack(some companies sell a dedicated rack injector, but just about any injector can be made to do teh job). Having a small amount of pressure on the resin helps to push air out of the crack ahead of the injector, and promotes filling down to the PVB. Resin and tape alone are not sufficent in my opinion to properly fill a crack. There have been many discussions on the forum on the use of "crack jacks" to promote a complete fill, I find the pressure provided by an injector to be a superior method to promote filling.

My 2 cents worth:

I have been in the industry for more than 3 years now and am still in the process of learning .... thanks to all of you out here.

I always carry 7 different types of resin with me from 2 suppliers. 5 of those are from GT (LV, MV, HV, CR & PF) and have no problems whatsoever with repairs. All resins work fine and its just a matter of getting used to the Resin and choosing the right one for the right job.

While surfing the internet a few months ago, I found an interesting company in South Africa (http://www.vitrifix.com) producing resins and am sampling their resins now, the other 2 (Penetrator and Finisher). I must say that I'm impressed with their stuff. It works as good as the Resins from GT and the end results of repairing is about the same.

The only thing which I'm not comfortable in this situation (after using GT all this while), is that I have only 1 type of Resin to do all repairs and then finish it with the Finisher.

Like what Yvan mentioned, I guess I'm just not comfortable in using the adjustable wrench method. Its just me and partly to be blamed are my customers too as the more complexed you get the more excited they are which is good for you and vice versa for your competitors. It all boils down to the way you market yourself and the kind of service & repairs you do.

As for repairing cracks, I've been using the 'Crack-Jacks' all this while and have no problems in accomplishing the repair task. Repairs have now lasted well over 3 years and still going strong ...

Pressuring the resin into the crack seems to be an interesting idea that I'm gonna try later on today, thanks to Yvan.

Hi there techs...I was just wondering if any of you guys actually take the injector out of the bridge and just run along the crack with the injector only and fill the crack that way.Hope this isn't too far off topic.

Yes in some circumstances that may be required. The only objection is that when you do it that way you could tend to press too hard and flex the glass. Another consideration is speed, moving too quickly is a disadvantage when performing crack repair, one must allow the resin to penetrate to the bottom of the crack before moving along. Plus having a base to support the injector allows you to leave the injector, to go cycle another injector, write an invoice, or scratch your nose ect.
