Are there any unique maintenance steps for the Seeker airbrush? 

Wipe the mirror-finished gravity cup clean after each session to reduce paint buildup and make future cleaning easier. During deep disassembly, remove the air cap, nozzle cap, and Quick-Release Nozzle first. Once the nozzle has been removed, carefully remove the needle through the front of the airbrush to avoid dragging paint residue into the trigger mechanism.
