Lubricate Material Control Knob

you'd ever really need to put any lubrication on the gland seal itself so typically what I'm lubing is the parts where that are that are I'm using back and forth and screwing back and forth so my material control knob on the back of the gun sometimes if I'm especially if I'm using water base uh it'll tend to dry out the aluminum and make it kind of squeak when you use it so if I put a little bit of Lube on that it'll make the threads work nicely and smoothly so that they don't squeak U so that's one of the places I'll use is on the back
