Great video, sanding the spring discs could help to reg refilling time ,but main problem of this regs is creeping and it is related to reg sealing surfaces, in this regulator, sealing surfaces are the black disk and shoulder of the shaft, if you remove the black disk you can see the shoulder ,polishing these two surfaces can reduce or completely solve the creeping issue
You can check with a digital pressure gauge. Or with a chronograph (make a few shots through the chronograph, leave it for at least 24 hours and repeat), measure the first shot after 24 hours. I have the first shot deviation +5m/s after 24 hours.
Yes I see what kind it is. Still don't know what grade and part number of this lub is to identify the technical specification. I want to know exactly because using the wrong lube it can self ignite while filling pcp bottle.
