Wayne,
you have that right!
i just can't figure out why i don't have the problems so many others do.
(not that i am complaining!)
i was going to say that "i can't figure out why they have so many problems", but that sounds like i am 'blaming the user'.
i shoot mostly Tamiya acrylics thinned w/ Tamiya thinner. (tan nozzle)
and Future (black nozzle)
i clean w/ tap water (run thru until no color comes out)
between colors.
and then when i call it a night,
lacquer thinner (small color cup full, shot into filtered jar)
i soak the nozzle in lacquer thinner for a few minutes as well.
i must be lucky.
