this is the brush; https://airbrushes.com/popup_image.php?pID=32ℑ=0&osCsid=fcc081467c37730b90a5c633f67574bb\ said:Now you say it just stops spraying, which would suggest that it starts to spray then stops. Correct?Model air should be fine out of the bottle, but I know there are some that thin it down more.
How is your air presure? I'm a bit in the dark as to what HP-BH is for a fish so specific help is hard to give. However a few things to try:
Can is spray with out stopping if you spray water (distiled) through it?
The air presure could be to low, and not being able to push the paint through the nozzle.
Does the paint in the cup or glass start to bubble; thats a sign of a blockage.
This was a problem I had a bit when I went over to Vallejo acrilics. turning the air up helped almost imediatly. Remember that the thicker the paint the more air you will need to push it through the air brush. Contra for fine work with better control, you will need to screw right down for the air and thin the paint enough to get it through the airbrush.
As I learned through the forum the best way to figure it out is to choose your paint and play with it. That way you get to know both the paint and the air brush. How much the paint need sto be thinned or how much air pressure you will need to get the result.
Hope thats some help.

Hi,\ said:
Who are you asking the question of?\ said:What size nozzle are you using?
Spectrum's great. ive got the liquitex airbrush medium but me thinks its time for more.\ said:Leslie that is a most comprehensive answer! You have most eloquently explained his problem. I can suggest a means of minimising the chances of such blockages occurring. I spray mainly Xtracrylix which are particularly prone to drying in the nozzle!I would suggest adding a drop or two of an acrylic retarder to your paint cup. I notice that you are in Solihull,if you can't find an artists supply store there a quick trip into Birmingham will enable you to visit an artists supply shop called Spectrum. It is in the under passage (Fletcher's Walk) by the town hall at Paradise Circus. They do the Liquitex range which work for me, they are also very friendly and helpful. These shops can be a goldmine for modellers so leave your credit card at home LOL!
Also, as someone else has said, there is no substitute for a bit of experimentation. You will find what works for you and wonder what all the fuss was about.
Cheers
