i am using americolor sheen in my air brush and it is splodging (lol is that even a word) i hope you know what i mean. How do i stop it- i have tried changing the pressure 

i wondered if i should thin the colour- but not sure what to use water or spirit. perhaps there is a tutorial on here but i can't find one.

I use the sheen airbrush colors all. the. time.  and I've never experienced "sploging".  I would give it really good, thorough cleaning and see if it helps.

I agree, give it a really good cleaning and if that doesn't help use some vodka to thin it...the higher the alchohol content the thinner it gets... I love working with the airbrush.
 

thanks for help. - it only seems to be splodging with the sheen colour- so i am guessing that it is because of the consistency so will try the vodka.

I am new to this gadget so if anyone can point me to some tutorials i would be grateful
