Now you're talking. The trouble with "rules of thumb" is that they cannot always be the right thing to do. I'm not comfortable with saying "5 drops" or "6 drops" of CA. Nor with "flex and apply drops" because I'm not going to presume that the wicking will oppose gravity well enough to saturate both the hinge and the slot.

But when you get comfortable in a well lit area and have good close visibility of the hinge you can see the CA saturating the material and can tell if its overflowed or not. If it has you've applied too much and you will discover that when you try to roll the wing over and learn you've become a semi-permanent fixture on the wing yourself.

So, I set up and even wear magnifying lenses along with my eyeglasses so I can see what I'm doing clearly. When I "dribble" some CA on this may be 2 drops or 6 drops...I watch what is happening closely. I also tilt the wing as I do it so that gravity helps pull the CA down into the slot on both ends of the hinge. All of this happens quickly. Move from hinge to hinge until that side of the surface is done, roll it over, flex the opposite way, and do all the hinges again but on the other side. If you are paying close attention you'll be able to tell when things set up. Then flex the surface gently at first. If after a bit you want to stop and move to the next control surface go ahead. Now that you've flexed it a bit you can always come back and work it some more. The main thing is to get it good and flexible before you hook up the servos. Pay attention to be certain all of your hinges are solidly in place. If you've read everyone's explanations on this thread you should have a pretty clear idea how to proceed and what to watch for.

Then you too can dabble with conveying this to a newbie!
