Okay, a few things:

1) Two drops was likely one too many. A single drop is enough for a square
inch of contact area.  Because of how CA works, more is not better, excess
glue doesn’t cure and/or becomes brittle.

2) For the same reason, gel is rarely useful.

3) Activator is not a scam, it’s just chemistry. But it doesn’t change #1.

4) If a little bulking in the joint is okay, baking soda sprinkled on it
works as a way less noxious activator than the spray. It’ll cure it
instantly. (This is a trick I picked up from Adam Savage’s awesome book
“Every Tool’s a Hammer”!)
