I'm not sure what you mean by the "original sight of the chip". But if there is anything black reappearing... a big spot, a line, or a lot of really tiny specks, then it was not done yet. There are exceptions in the real world, such as dirty, contaminated breaks that don't let the resin soak in like normal.

One thing to try is remove the injector when you think it's done, but don't cure it... just wait and what what happens. If it stays filled (clear) for a while, say 10 minutes or so... then you know it's done. I'm guessing by what you say that after a couple minutes, there will be areas reappearing... still air in the break. Then try "cooking" it again, and see what happens after that. Play with that and you might get a better idea of when it's properly filled and ready to cure.

Disclaimer: Guys, this is just an idea to try, and exercise to maybe find a solution to a problem. I don't what to have to explain/defend myself or my resin or techniques. Thanks.
