Several of you say that a real stupid question is that question that is not asked.. so I'll begin with my stupid questions.. hey after they are answered they won't be stupid anymore.. they'll be a little bit smarter...

OK, so what is the difference between using a paint bottle or a color cap? When should I use one or when should I use the other (I promise I have searched the internet for this and the airbrush manual does not say anything either

Is it just a matter of taste? Is one easier to use than the other? The basic airbrush guides on the net i have seen do not address this.
Thanks
