Have used the above with great results. I don't frag much, and usually only use it for repairs or gluing down new frags. Starts off runny when you open it so I usually push the tube around a bit to give it a slight mix, and the larger sized tubes are good for maybe 2-3 different times before the tube cracks open or gets too clogged.
Just got the poly lab stuff from you and like the consistency so far. Smaller sized tubes seem to be better for small amounts of fragging.
