okay so I think I'm ready to go. Only one question, do I just spray the Aquanet down the open end of the "gun" and then seal it quick with a potato or what?

Correct. Spray for about 2-3 seconds. Of course I don't exactly know how big your firing chamber is so you'll have to do some trial-and-error to get the result you want. You don't have to be quick about sealing up the chamber. good luck.
