I use one of those clear nozzles supplied with various tubes of sealant or no nails, unused of course. Most come with a screw cap and if you fill it, then put a bit of insulating tape over the larger open end it provides a nice dispenser. Make sure you don't cut too much off the thin end and all you have to do is hold between thumb and second finger and gently tap with your first finger - very much like tapping ash off a cigarette. It's very controllable and you can put it exactly where you want it, especially around points etc. To fill up simply undo the tape, scoop some more out of your storage container, put the tape back and away you go.
