Removing CA from fingers
I always keep a bottle of debonder handy. Its basically 100% nitro, so I would imagine that if you were REALLY stuck you could try some model fuel.
More importantly, I almost always wear gloves when glueing. Its amazing how far down thin CA will wick and there are a couple of places on my airplane where there is a small shred of nitrile glove stuck to it. That represents saved skin!
The cost of the box of gloves is more than made up for when you think of how some people develop alergies to CA, epoxy, etc.
