Hey Garry....
I only use the applicaters in areas not easily reached with your fingers. I normally mix the Aeropoxy in a small cup with a stir stick and then apply it with a artist blade spatula. There is a certain amount of wasted material in the nozzles that can not be recovered. You can store the nozzles in a freezer over night, and use them one more time after thawing out.

Have Fun!
