Duster Propellant "proscribed" as a green house gas
I have a friend who is in the heating and cooling business, he says that the propellant in some types of Duster, Tryethyl--bla-bla has been proscribed as a green house gas and current stocks won't be replenished.
They are not pulling it from the market so much as simply not making it any more for distribution in Canada.
the Diethyl--- bla bla version has not been proscribed yet.. and is still avalible, but not a viable propellant for guns due to a lower coefficient of expansion.
Anyway... propane is the way to go..
