A little late to the 'been there done that party' but I've put more than one nice glue fingerprint onto a beautifully clear canopy, or top of a nicely painted wing, or ran a drip of cement down the side of a fuselage. Oh yeah. Been there. Got the fingerprints to prove it. And is irritates the hell out of me when I do it.
When gluing now what I use are those white tube ends. You can get a mess of them from MicroMark and they are like little dishes. They call them 'Mixing Pallets' but they are the plastic ends that go in tubes for shipping. $9.95 for 40 of the suckers.
I use them for pretty much everything except Tamiya Extra thin and the black Model Master glue with that long metal tube - I'll put a spot or two of whatever else i'm using (CA, Gator Glue Gel, etc) and work from the little dish using toothpicks (mostly) or micro brushes to transfer the cement where I need it. I even put a drop or two of paint in them when I'm hand painting. When dry the paint scrapes right off.
Not sure if they would work for you but I use them all the time now.
