Windshield Repair Forum

Were the extended legs surface or sub-surface?

There are several factors which will affect how a star break reacts when you start to repair:-

1) Position on glass - a SB in the middle of the glass will have a higher "run" risk than one near the edge due to glass flexing.

2) Temperature - if the glass is too hot, the interlayer softens, allowing a greater amplification of any pressure applied by your equipment.

3) Pre-stresses - the glass has already, inbuilt stresses, created during the manufacture of the glass. The " run" risk might be already very high because of this.

Pre warning the customer, before you even touch the glass, is a must when you have this type of break.

Create, as much as possible, good access at the entry point for the resin.

If you have to remove moisture, be very careful when heating and make sure it is cooled down before applying equipment.

When you begin to apply pressure watch the for signs of running intently and back off immediately to avoid it. Better to have a longer repair than a longer crack.

I find that replaced glass (not the original windshield) is more susceptible to cracking during a repair.

I would add more resin to the injector. This will provide more pressure to push the resin further down the crack.

I did actually add more resin to the injector so I could push it further up the legs.
When I pulled a vacuum, the resin would retreat out of the legs again.
I did another repair the same day on another WS and it went fine.
Most of my repairs are effortless.

I will ask again, were the legs surface or sub-surface?

I was unable to feel them so I will assume they were sub surface.

I thought you said the resin pulled out on vacuum, this would lead me to think air was getting in along the top. If this was the case then a few drops of resin as in how you would fill a crack. Now if the resin was not coming out but air just moving backwards and forwards I would say that plenty of time should have got the job done, presuming premature curing did not occur.

Did all 3 legs run at the same time or 1 at a time?

Never mind.
This is a forum. Not a murder inquiry.

I feel ya, Mr. Bill.
