Windshield Repair Forum

I encountered one of these yesterday:



The small pit was completely disconnected from the bulls-eye (which only the edges were visible) below it.

After much probing, pressuring, and heat, the ding refused to connect with the pit. I resorted to drilling, punching a mini-bullseye--- which still did not yield the results.

After that, I filled the drill-hole and left it alone. There is 100% certainty that this ding was not previously repaired.

I hate defeat.

Does anyone know these sorts of dings? What can you do?

I would drill an pop a mini bull at the bottom or end of smiley face and use pit filler on impact area. I have had pretty good success with this method.

sgaily, feel for the area other than the pit area to see if it is a surface break? If it is, then you could try feeling it like one of those cracks.

IMO, it sure looks like a previous bullseye repair that hadn't been dried out prior to pushing resin. Initially, it will look filled but give it a month or two and the traped water at bottom of cone will evaporate leaving what your seeing (air). I see these all the time!

Screenman...your turn to comment

Amazing! I had the very same one today!!

Ok, after trying to fill, drilling the pit (no success) I did what vinyl-4ever suggested, I drilled at the dottom of the visible circle, popped a bullsye and filled! after filling I used a large mylar square and pit filed both holes at the same time.

I maybe should have charged for two repairs..lol

A bullseye is different from other breaks they are really a funnel break in the glass think of upside down funnel solid in the middle (thats why drilling the center doesnt do much good with bulls) like a star or bat the end of the break is thinner with a bullseye I leave the injector on a while after it appears filled and then pressure cure I know some mfgs have a strong dislike for curing under pressure but it works for me and leaves the ends circle free

Thanks for the replies, guys.

I went over it very carefully--- the fracture is definitely beneath the surface.

That's exactly what went through my mind when I first clapped eyes on it!

However, I studied it very closely, and was unable to detect the characteristic ring-shaped scar of a previous repair. The area around the pit and the wings at the bottom was flawless!



Also, I felt the pit for previous resin (which feels soft when compared to the glass around it), but could detect nothing.

GlassStarz... this method eliminates the ring like I described above?

That sounds capital!--- are there any downsides to curing under pressure?

And how do you get the lamp around the injector? (doesn't that cure the resin inside your seal, too?)

I agree with the posts... provided that the smiley face was normal size (3/4 inch diameter or less) if on the other hand, it was one of the 3-inch diameter mega pressure breaks... kinda different story. I usually drill both ends of the smile and inject them full... on some I eben have to drill every inch or two...

When I see this type of break out comes my mini torch. 90% of the time it's full of moisture. Let it cool and fill the bulls-eye!
If drying out this type of break is not successful, do what Viny-4ever suggested.

Sgaily, your illustrations are good. I tip my hat to you for the extra effort.
