Windshield Repair Forum

I'm not sure if this should be a new topic, however I have read through the posts on hard time filling in cracks, but this topic don't cover what I'am seeing on my practice glass.
To start off I'm working under perfect conditions, no UV problems, glass at 70* , no pressure to complete repair in timely manner (practice glass in basement), cleaning pit with scribe, maken sure legs go it pit, using a horse hair brush to remove ang glass particles in pit, align bridge and injector correctly.
I use GM injectors so I start on a vaccum cycle, go through all the steps I need to, to make the repair. While on the pressure cycle I apply presure to the legs to fill them, I do this a number of times till I see the leg fill in all the way to the end and the bright refection are gone while using my pen light. I cure under pressure from two sides for 2 min. each side, put a slight vacumm on Injector and remove bridge, apply pit filler and curing tab, apply UV light, then finish the repair.
Sorry for the build up, but heres my problem, when I am finished and inspecting the repair with my pen light at certain angles the legs don't look filled in, but I know they are because I watched them fill in while applying pressure with my scribe, there was no reflections in legs before I cured under pressure and finished my steps. The legs are not visible seen until I use me pen light. Am I to picky? Could It have something to do with the pen light? Any hepl would be Very helpfull.

We don't recommend curing under pressure when using a Delta Kits system, so just for fun try "not" curing under pressure. Many disagree with me on this but when the injector is mounted on the glass there is pressure against the glass that can partially close the cracks. When you remove the bridge, the pressure against the glass is relieved so you can see if you truly got the cracks completely filled or not. If not, you will have to continue with the injection process, but if the break looks completely filled and there is no light refraction from the cracks there should be even less after curing.

The refractive index of the cured resins can also make a difference, or as you said, you may be just too picky. It's rare that you cannot see cracks when using a pen light from certain angles, but with the windshield repair resins we sell the cured resin should actually look better than the uncured resin.

With a Delta Kits windshield repair system we call curing under pressure "cheating" because even if all the air is not out of the break you can make it look pretty good, although often temporarily, but if the manufacturer recommends curing under pressure with their equipment you have to assume there is a reason why, so be sure to experiment with not curing under pressure on practice glass only, and if this does not work go back to following the manufacturer recommended procedures and contact them for assistance.
