Yes the posts are there. There are no insults. Criticizing your airbrush isn't insulting you. It appears you're a little touchy about your Neo. Buyer's remorse? Not my problem and don't take it out on me.
Tip dry is a fact of life with most acrylics, and can only be mitigated to an extent with a flow improver and drying retarder. I use Liquitex products which outperform most of those agents offered by the paint manufacturers. Regardless, nozzle design and machining tolerances can make certain brushes more susceptible than others to tip dry and resultant clogging. Nozzle design can also have a marked impact on ATOMIZATION. These issues diminished significantly when I moved away from Chinese brushes such as the Neo.
