ring around the bullseye

hmm, thats kind of odd how they will go away with a simple pressure cure but very nice knowing thats its worth a shot at least

Just incase some of you who read this topic, i will post a photo of how to tell apart the windshields here a bit later just incase youve never encountered one before.

The ''silverish'' ring will not disappaer.
And a little extra pressure only works with GW/GM injectors.
In fact: I was trained in using both systems and it was part of our training.
I believe it is NOT recommended by Delta Kits.

You may have told us before (sorry), but what is the system you are using Cryatal_Image?

Funny I find curing under pressure increases the chances of a pressure ring. The excess resin pushes the cone back into the PVB which of course we all know contributes to the cause of the ring.

''Just a little'' extra pressure Screenman, just a little.

We were told, back than, that the resin would shrink a little while curing.
So with a little ''extra pressure'' we would stabilize the situation back to normal (those injectors ''press'' a little extra resin into the uncured break).
The shrinkage-situation would be reduced to zero because of a little extra resin. You kinda ''overfill'' the damage.
This is GW related stuff from some sixteen years ago.

Just to clarify, you "can" cure under pressure with any system. Delta Kits does not recommend curing under pressure because you never truly know if the break is completely filled until you remove the pressure from the surface of the glass at the impact point. If the break is filled properly with a quality resin you should not be experiencing any air space around the edge of the break due to shrinkage. Air around the edge of the break, prior to curing or after curing is only there because you did not remove it in the first place.

Back to the subject, the white ring is not air space so adding extra pressure is not going to get rid of it.

I have an equalizer kit. That RING was there before i even started guys. That "HALO" has nothing to do with what i did or didnt do. Not sure what else to say. Its not a void to be filled. Would be like chasing a rainbow to find a pot of gold at the end. Would be nice if i had some sort of logical explaination for it or a cure but i do not.
Anyone know of a quantum physics major?

Several of us have already provided the explanation; the solar coating is damaged. Thanks for verifying that it was there before you attempted the repair; if you mentioned that before I missed it. I agree with you, there is nothing you did or didn't do...or could do for that matter, except perhaps to explain to the customer in advance that the "halo" will not go away. Next time you'll know.

Thanks Brent. ACtually, it was on my wifes van. As previously stated, its been there for approx. 6 months. I was always to busy to fix it. TO busy with work and trying to make a living. Maybe its due to acid rain/moisture, salt, air polution, etc some kind of reaction to the outside elements; maybe It could be a reaction to light much like a prism or diamond has. I just dont know

Knock a couple of fresh breaks in the windshield and see what happens with those if you fix them right away. (:
