I used to keep a smal tube of Badger airbrush lube handy for lubing packing and the needles on my guns and it worker great, especially on my primer guns. Primers like PPg K36 and the Standox hi-builds that set up like concrete would gum them up but the lube kept everything flexible...I even coated the threads to the caps with it to keep anything from binding them up
