Gabo,
Do you have a drugstore around?
You can use glycerine to lube the airbrush if there is nothing else.
A bottle of Badger Needle Juice or Medea's Super Lube will last you many years, so if there is any chance of getting some go ahead and pick some up.

“Wisdom is the right use of knowledge. To know is not
to be wise. Many men know a great deal, and are all the greater fools
for it. There is no fool so great a fool as a knowing fool. But to know
how to use knowledge is to have wisdom. " Charles Spurgeon
