Bullseye SNAFU

[Mark]

Today as I was repairing a bullseye I was able to completely get rid of all the signs of air by pre-filling and pressure with the probe, all the black was gone. It took a couple of minutes and pressure with the probe on and off to get the resin to fill the break. Being new I decided I had to put on the injector and vac/pressure, then the bridge came lose so I put it back on and redid vac/pressure, cured under pressure and when I lifted off the bridge had air back in the break, new guy mistake, I know now I could have refilled the injector and the break then cure.
So here is my question. Did I really need to apply the injector when I had all of the air gone prior to the injector being set? Could I have saved time and still had a good repair and went on with the cure cycle?

BTW
I was not really working today, today was to be a day off, without trying I lined up an ins job, will trade a w/r for a full massage and will get a website built for a quick repair I did at the paragliding field. 3 jobs on a day off.
What a way to make a living.

Nice going Mark!! Those are the success stories that keep me motivated and not give up. Hmm...this gives me an idea. Instead of giving my friends actual free repair, I'll trade them for beer or canned goods.

Mark, you made that fatal mistake of pressure curing when the injector was out of resin. Bad... Of course, if you don't pressure cure, then this can't happen.

You can probably go ahead and just cure it next time w/out using the bridge at all, IF the bullseye really is completely filled... no black at all. But before you do, keep it covered up for a minute or two and see if it stays clear. If so, then go ahead and cure it.

I would always stick the bridge on it briefly to be sure it's really filled... just a few seconds and slide away to check it. If it's clear, remove the bridge and cure... nothing bad can happen this way. 8-[

Thanks for the replies. It was interesting to see that ole bulls-eye go away working it just like MASFU aka Chris taught me using the pre-fill and probe pressure. But had to do more I thought.

Any way I am sure there is much more to learn.

One more thing, before I started the repair and let him know this was more for the structural integrity than for appearances. Should see about 80% or more gone from view. He was very happy with the repair. And I would have been too if I would have left well enough alone.

Mark I usually will use the bridge after prefilling a bullseye. Use it just to make sure the bullseye doesn't suck any air back into it they will do this from time to time. Did you put resin in your injector after you applied it over the pit? I usally pressure cure a bullseye for a minute or so then remove the injector and finish curing befor I apply the pit resin.

Repair1 here's a definition of snafu I found.

Chris All was going well with the repair, I was on track procedurally, just when the bridge came lose and I lost the initial connection. I went through vav/press again without refilling the injector. So I was working with air only. I had to put air back in because that was what was in the injector at the time. The thing that saved my bacon at all was I had pre-filled and worked the break like you showed me, so most of the repair was done. I think (now that's a scary thought) because the BE was filled already I was only able to force just a small amount of air back in, no place for the air, the resin was there.

Also that is good to know that they can suck air back in and to pressure cure.

Happy Easter to you and yours

Mark I think you told me you had GM equipment. The bridge coming loose from the windshield during a repair would really bother me. I believe some of the folks here also use that equipment. I was wondering if anyone had any tips to keep that from happening?

I think I did a poor job of wetting the suction cups. This was the first time that I had it come lose. All of the other time I have used it, what a bear, those cups were on tight. I want to get a small spray bottle like you use, I am sure it will help.
