sgailey,
Any chance you have pictures of actual damage on this shield? Are you playing with all of us on this one? It's definately an unfilled bullseye, whether you choose to agree or disagree....that's what it is!!!

Like Wilz stated......illustrations are good! But I find actual pictures to be better.....when trying to resolve repair problems.

Sgaily,
If the "smile" is more than 1" away from the impact point it's not a bullseye type break. I repair many of these. IMO an object hit the screen and pushed down the glass causing a circular or curved crack. Most of the time I can feel the break and I fill it like a crack - drill a hole in the center of the crack and inject resin. Sometimes I will pop minis at the ends, too.

This type of damage I call a blind break, because the actual damage is on the inner face of the glass and not connected, at any point, to the surface. The advice given by vinyl-4ever is exactly right. The only extra advice I would offer is to perform moisture removal process prior to starting just to ensure there is no damage being obscured by moisture, and confirming it is a blind break.

What--- and waste everyone's time in addition to my own?!
I think not.
Otherwise, I agree that this is an unfilled break!--- just one unlike I've ever encountered before.
And I apologize to everyone for the lack of pictures, my digital camera has gone missing for its 4th week, now. You'll just have to take my word for it on this one. :eusa_ange
Just to clarify, there was no breakage on the surface above the fractures. It would seem that this is a completely isolated sub-surface fracture like the one
AGSS described earlier in this post. Drilling and filling seems to be my only option at this point seeing as I've already filled the pit.
Once again, I thank everyone for their patience and those who gave their advice so freely. This is indeed a healthy, supportive community!

Sgailey, not to offend you or anybody's elses opinion concerning this damage but I will ask you to try this test on your practice shield (if you have one)
Simply pop a bulls-eye and don't drill (because bulls-eyes don't require drilling!) fill it with water, dry it out (but not completely, like 70%) Start your repair as usual, cure with UV and when your done.... everything will look just fine and totally filled! (a typical car wash repair)
Has this repair been done properly? No not at all!
Give it a few weeks (or to speed up the process use your drystar again after a few hours) Guess what will happen? You'll see the same thing as being described!
I see these all the time in Michigan, especially during the winter months when other techs don't completely dry things out prior to filling. You can't get resin flow through the pit area because it's filled and cured. You'll have to drill into each air pocket to accomplish
this.
All follow up responses and opinions are welcomed;)

I have seen this type of damage very often. As someone else said just drill at the very bottom of the smile pop and fill. This damage will have no moisture in it as it does not surface anywhere. I agree and bad repair can come out looking something like this, but in this case it is new repair untreated before.

Screenman,
What do you mean, this damage will have no moisture it does not surface anywhere. There is an impact point. The ones that I see (as in diagram) have moisture that must be evaporated first!

vinyl-4ever & screenman, I agree with you. It's actually a pretty simple repair. I've done breaks like this before. I think it's getting over diagnosed here. The damage is not even close to being connected to pit.

Screenman,
Please explain how you came to that conclusion from just looking at this illustration?
This isn't a actual picture of damage. In all my years I have never seen a bullseye this small as new damage look like this unless it was a;ready filled and cured with with water still present! You know as well as I....water will evaporate over time, leaving a void. (air pocket!!!)
You see these commonly, because in your always wet area others don't dry them out properly.....which you've stated in many previous post! This was a bullseye, filled and cured without total dry out! Plan and simple! Sgailey already admitted to that.....so why are you saying something other?
