Super Lube is a natural and non-toxic airbrush lubricant. It contains no petroleum or silicone additives. It can be used on all moving parts of an airbrush. Use on the main lever, needle packing and valve-piston packing to keep them moving smoothly. Apply in the needle cap and along the needle to enhance paint flow and prevent tip drying. Will not affect or react with any water lacquer or enamel based paints. A must for any airbrush user.
