Hope your all enjoying the fireworks
okay my question is what is the correct procedure or way to repair a windshield?
I work as a windshield repair tech for a company and the way I was tought was this: if it is a star or a bullseye
1 I drill a tiny hole where the star or bullseye is
2 I then try fill the hole and the cracks that were originally there with the first of two resins with an injector type mechanism that is attached to a suction cup. I also put a mirror on the underside of the window to see where exactly I'm injecting the resin
3 I then pour the second resin (which is a more concentrated version of the first resin) over the hole that was drilled by me
4 Then I put a small piece of clear plastic over the hole with the resin and let it dry. I try to do this in the sun, if I'm not able to, I use a uv light to dry the second resin
Is this the correct procedure?
I thought the air had to be taken out of the cracked area of the windshield.
How do you do it?

Re: What is the right way to repair a windshield?
Basically you are correct. But yes you need to suck the air out of the damage with some type of vaccuum pump or device. There are many other factors involved as each repair is "different" and may require a certain technique to have a successful repair. What I don't understand is why you use two types of resin on a bullseye or star. I thought that was used only when repairing small or large cracks.

Re: What is the right way to repair a windshield?
The first resin that wrtech is talking about should be the resin that is used to fill the entire break. I have had extremely good results using Delta's Premium Bond Resin as my only resin of choice for stars, bullseyes, batwings, small cracks and even 6" cracks.
The second resin that wrtech is probably talking about is the Pit Resin that is used to fill the pit on every repair, (not the body of the break).
wrtech, I don't see anything wrong with the outline of steps you take. It's the readers digest condensed version of a repair, but it looks like you got the idea.
As far as getting the air out, some systems use a vaccum first method, then pressure resin in. However, Delta's system of pressure, vaccum, and pressure again seems to work the best for me. Here is an anology of why I think Delta's system works over others.
... When you fill a drinking glass with water, do you vaccum the air out before you try filling it with water??? Of course not... thats because the air is pushed out of the opening by the water pouring in. It's simple physics.
And if there is any air trapped in the repair after pressuring resin in, the vaccum cycle will pull it out before you do the 2nd pressure cycle.
Hope that helps.
