What I wonder about is what they use for the propellant.
If you wonder why I think about it, read up on what tends to be in aerosol cans and what that stuff will do to an airsoft gun.
Silicone oil is available pretty much anywhere in Canada, and even Home Hardware has parts that can fit airsoft guns (piston rings are no different than plumbing gaskets)
So you dont need to bother with that stuff.
