Doggy,
Many thanks for your reply.
Firstly, big problem now for me is that i have stripped my airbrush down and found 2 'O' rings damaged.
1 'O' ring sits in the needle guide and the other is a small one that sits (i think) next to the air cap body.
I think it is where i was trying to push the needle back in and it has pierced them !

and it costs £2.00 each 'O' ring !!!!!

($4.00 to our American cousins

)
Right Doggy, i use an AB-180 airbrush which is for fine line work.
Everything Airbrush
Vaseline, would that not rot your O rings as it is petroleum or am i wrong ?
Though i did not know you had to but it does make scence.
How about K.Y jelly ? Would that be any good do you think Doggy ?
thank you
andy
