Stubborn Legs

[Sylvi]

I live in a tropical country Srilanka, Pioneer Windshield repairer from 1992 with "NOVUS" USA method. have done more than 15000 repairs have come across lots of Star cracks with legs do not fill Resin. What I do is to drill end of the star leg with a very small drill bit and inject from that hole the Resin this is done only if the customer is willing to have another hole on his windshield. if not I do all methods mentioned on previous posts.
The best to do a as far as I practice is give less injector pressure on the glass
and get maximum piston pressure to not to over flow resin on the glass,
heat up very little on the top of repair immediately get into the vehicle lift the glass cracked point from the back of the windshield without extending the cracked leg give a gentle tap on the glass for the resin to flow this is repeated number of times until the leg get filled with Resin
If any one in the forum can comment of my experience please give your comments.

In the last week to ten days I have had about 4 repairs that just gave me fits. That's out of maybe only doing about 18 to 20 repairs, so not a very good average. I think one was an attempt at a re-do, so had an excuse there, but the others were just not going to fill period, even though I did all kinds of things in the process: drill deep enough to make sure I got to the legs, use the moisture evaporator on at least 2 of them, pop a bullseye on maybe 3 of them, give more time, heat on a vacuum cycle and at the end try to heat to fill, and re-drill at the ends of the stubborn legs to fill backwards. In the end I was no better off. Do you all run into a rash of these?

I am sorry to say this but I cannot remember ever doing a starbreak that would not fill. That is as long as you have done all the preperation properly.
You must be doing something wrong somewhere, I know this sounds harsh and I apologise.

I have to agree with screen they all fill .I have to wonder if you are getting a tight enough seal so you get enough pressure to push it in? new seals are often the cure with time and pressure combined with several vac cycles things should be filling.
We all fall into habits and methods that make things easier but sometimes dont give as good a result For myself I go back to square one and pretend I havnt done a kazillion chips and do the basics step by step I had a Salesmanager years ago tell me "if you cut corners long enough you end up with a circle and that isnt the goal here" and trust me I am the first guy to try doing something the easy way LOL Break down your equipment clean and replace seals then go to the begining I bet they start to look better.

No offense taken Screenman or GlassStarz. If all it is needing to change the seal, I'll eat my share of humble pie and be thankful. I haven't changed for a number of repairs, so very well could be it. That with a good thorough cleaning

I must relate to this also.I was also having a problem at times filling legs.The biggest help I found even living in an area that is hot and sunny most of the time is that now I dry out EVERY repair.This simple part of preperation on a repair has made my repairs problems virtually go away.This and paying attention to injector seal condition and seal pressure at repair area and making sure that my repair area is UV shaded(dark towells) has made all of the difference.Screenman has always preached "when in doubt dry it out". Well now I joined the choir too !! LOL

Yep, much better the last 2 days since changing seals. Thanks guys

[Spike]

How often do you guys recomend changing the seals?

[GlassStarz]

When they start leaking is when i do it the mfg says more often something like evry 25 repairs I find since moving hee I go through alot more of them that 100 degree sun makes the glass hot and softens the seals.
