Are you repairing the crack outside? In direct sunlight? What viscosity of resin are you using?

I have a special room for glass repair in I use the resin "CR".

Have you asked the customer how old these repairs are? The older the repairs the more visible to finished result will be. It may be beneficial for you to call GT support and have a technician work through a repair with you.

vtrex, have you solved this problem?
If you are able to get a broken w/s from an auto glass company, I would suggest making a few different cracks to practice on. I've found it very useful to practice drilling techniques without worrying about ruining a customer's w/s.

What kind of injector are you using for your crack repair? I generally will not repair a long crack older than 1 week.

From my experience there could be a couple of things wrong. One could be that your expectations and the customers expectations are to focus on the cosmetic benefits of crack repair and no the crack doesn't completely disappear after the repair is done, or two that the repair is actually failing and so there is not visible change.
Your customer's expectations are set by you and maybe how you are advertising. You don't want to advertise that the cracks will magicaly disappear or allow the focus to be on making the windshield look better at all. Instead the focus needs to be on saving the windshield from needing to be replaced by preventing the crack from spreading and reinforcing the broken area.
Having said all of that, there should indeed be a significant reduction in the visibility of the crack after the repair is complete. The difference is primarily in the appearance of the sidewalls of the crack. When you look at an unrepaired crack from a side angle you will see greenish-black wall running the entire length. As the crack is filled with resin the appearance of this wall changes from greenish-black to a silvery-clear. Once the resin has cured there should only be the appearance of a thin silvery line at the surface of the glass. It almost looks like a fine scratch. You may have to bring this visual change to the attension of your customers by allowing them a good look at the before, during, and after results. It could be that they just don't realize what it use to look like.
Now if your repair are not turning out the way I descibed then there could be some other problems accuring. It could be that you need to hunt for a better resin, or that the cracks are not filling in properly. I use only Diamon Clear CR (crack repair) resin from Glass Technology. It very clear and has a super high tensil strength. I also use a special needle cap supplied by them to help apply this resin.
If your crack repair are failing then it could be that you are repairing the wrong kind of cracks. Stress cracks are cracks that have no point of impact because they are do to stress created by improper installation of the windshield. These types of cracks cannot be repair because they are highly likely to fail. Impact cracks are the okay ones. Another reason that crack repairs can fail is due to contaminents such as waxes and detergents that can get down in the cracks. These can affect the lower the bonding capabilities of the reason. I will usually ask my customers a few questions to determin if this could be the case. Since the crack occurred have they, taken the car to a car wash, used their windshield wiper fluid, and how long has the crack be there. Depending on the answers to these questions, I may use a cleaning solution which is also a Glass Technology product. Its called Xtra-bond Adhesion Promoter. It has a mild acid mixed into a solution of high grade alcohol that helps to disolve away waxes and detergents. It also finely etches the glass to give the resin a rough textured surface to better bond to.
Well I've certainly rambled on long enough. I hope that some of my experiences help. Don't let your customers set the expectaions. Most of them don't know shit. You're the expert, so tell how its going to be then make good on it. Don't let them decide whats a good repair and whats not.

Sounds like you know your stuff. How long have you been doing repairs?
Anything else to go with it as a side line?
