how many times have you used those 5 min epoxy syringe type dispensers and they don't come out evenly from each tube, then you mix them both together apply it to what you are gluing only to realize hey not having the same amount of both parts don't dry to darn quick.......don't know why i didn't think of this early i guess it didn't upset me enough to do something about it, so i cut the darn sections to be on their own...now i can put the same amount from both tubes....
