advice needed from the airbrush experts please

[braddaz]

Hi to you all ,

in process of airbrushing my first body shell when using airbrush to do fine line i have noticed paint flow stops , i have to increase paint flow right out an then reset it to fine again it gets very annoying using faskolor paint ,
is it too high air pressure for paint flow or does any one else experience this

thanks any info would be gratefull
will post a pic of me shell when done , well jealous of the quality of paint work on here
