Two questions about the guns:
1. What makes them easier to clean out than the plastic nozzle
supplied with the can?

You buy a can of cleaning solvent that mounts on the gun in the same
way. So after each use you flush all the foam out of it with the
solvent.

Ahh, I see... thank you.

2. The main problem I find with a part-used can is not with the
nozzle at all, but with the liquid inside the can very quickly going
treacly and losing its fizz.

That seems to be caused by the can leaking its propellent through a non
sealing valve.

Funny, they all seem to do that for me, and there's never any obvious
evidence of leakage.
