Windshield Repair Forum

Splitpit chill out, the reason why it is a good idea to respond is so that someone else with the same problem would not have to post an identical question at a later date.

Also where I come from it would be out of politeness to the people who took the time to write the suggestions.

Oh! and by the way part filling drill holes is another good way to avoid air bubbles.

I'm chillin like a frosty brew! No worries!

Im sorry guys I havent responded, but I had an emergency trip overseas and Im back. I did few repairs yesterday and only the ones I drill still come up with the same air bubble!!! I have been trying everything. Extra air suction, put more pressure on injector, put new seals in, doing extra injections and suctions....

StarQuest you mentioned you had the same problem. Would you be willing to describe what you have done to fix the problem??? Thank you all for responses!!!

I think Im gonna have to pull out my practice w/s and try everything you guys tell me!!!

If the rest of your repairs are filling nicely and all that is left is that little tiny dot, then you're doing pretty well. Don't think you should do drastic things though, like increasing the pressure. It'll come in time. I know some others think differently, but I like to put the pit resin in before the regular resin is fully cured. That way they kind of blend together more. Not trying to confuse the matter. Just saying you can try some different things, just don't get too drastic with it.

Right for sure I am not going to get you to try new resin, so how about this.

Instead of pit filling to the top do it in 2 or 3 stages filling only a small amount each time and curing for a minute, only apply curing film when you are on the last fill. You will find this method works well if done correctly.

Hi Gang,

If it is only in the ones you drill. There a couple of things to think about. First, your drill hole itself is going to be quite visable, so drill as shallow as possible(or not at all). Second, remember that when you drill, resin will often drain from that drill hole and leave a small, shiny, or black air bubble. Pit resin is just too thick to flow down into the bottom of your drill hole, so that air is just trapped there.

Solution, don't drill unless you can't get the resin in any other way. When you do drill, make sure you never go deeper than 2/3 through the outer lite. As screenman suggested, when you do drill, try to make sure the bottom of the hole is lower than the top, so less resin is apt to pour out. Even if you have followed these directions, it is still very likely that you have left a small air bubble under your pit resin that will be very visable after you have cured. So, you have to get it out of there. As you are applying your pit resin, take a sewing needle and push it down through the resin to the bottom of the drill hole. Pull it up slowly and allow the bubble to rise with it. When the bubble comes to the surface, use your needle to push it away from the pit area. Voila, no more drill hole bubble.

Thankyou to everyone that has taken the time to help Gedis. It makes me proud to be associated with you guys.

Thanks Matty and thanks everyone!!!
Well the problem is, when I apply the pit resin, there is no air underneath it. It only occurs during the curring process so there is no way I could pull out that bubble cause the resin on the outer layer already has hardened. But I will try to use needle to squeeze in more pit resin in there.

Gedis have you tried any of my suggestions? another one is let the pit fill cure without putting a tab on top, takes a bit longer but works. After this post I give up, mind you it is not something I have a problem with maybe I am doing some different.

Dear Gedis
What screenman said is absolutely spot on, if you took the trouble to actually read the advice given to you the problem would not persist. I am going to unsubscribe from this topic. Stop wasting everybodies time.

Ouch that hurt.
