Where is the best place to buy the Iwata Medea Lube for their airbushes? The little tube that came with mine is about gone, and I've only foud one place that has it, and they wanted more for the shipping than the cost of the lube . . . .
OR - is there an alternative (read cheaper) type of lube that works as well? I have the Iwata HP-CS airbrush, and want to keep it in top working order.
Thanks,]
