I'm thinking that I might try dipping a fine needle pair in masking fluid.
See if it stays on, and if it holds small pieces better. To my thinking, it all comes down to grip versus pressure: squeezing too hard makes the pincers either slip off or cross each other, launching the part into orbit.
So understanding this, I try to not squeeze too hard, and keep the pincers aligned: this is a lot to think of when trying to place the part with one hand and holding the glue or another part in the other!
Almost like I need a finger controller like the adjustable torque on my drill.
