Where Swim is from, Colemans is the NP of choice.
It is used straight from the can with no problems, and gasses excellently.
After gassing, Swim would filter product through 3 coffee filters and squeeze the hell out of them to get it pretty dry, then set on a mirror or other surface to air dry.
He has never seen any problems from Coleman's, other than this one time when he get some blue meth, but he didnt make it, he just got some, so he doesn't know what happened to make it blue, the guy who made it said it was blue from the coleman's.
Swim has never had this happen to his stuff, he thinks it may have just been because of the type of pills used.
blar, blar, blar...
