Review on MG Chemicals Dispensing Gun Cartridge by Brent Henderson

Didn't know cartridges, guns and mixing attachments were special. Oh my god this is so much better than trying to mess things up on the board and then figuring out how to do it in tight turns! You only lose about 1/2 "click" to hang up, so not much is wasted. Very effective compared to other methods I tried which were much more tedious and wasteful. At the end of the first tube you finish, mark the black plunger so you know when it will run out. :-)
