OK, since many have asked, and it seems to come up in nearly every thread now, here is how I have ALWAYS maintained my Wrath. I know it goes against what Toolshed said to do, but again, I have not had a single problem with mine, so it must work. I started doing it this way before Toolshed even posted a maintenance thread, and have stuck with it since.
PMI MARKER OIL (A.K.A. EXTREME RAGE OIL) OR EQUIVALENT IS USED IN THIS METHOD
Bolt--I have an aftermarket Nylatron bolt (the no longer in production, ever so rare, Spudnuk'l/Spartacus Nylatron item). Remove the bolt and place one drop of oil on each o-ring and spread it around by finger.
Reg--TWO drops of oil into the macro line fitting screwed into the bottom of the reg (Evil Detonator), prior to attaching the air.
LPR--First, disconnect the LP hose from the LPR. Unscrew the LPR from the LPR adapter. ONE drop into the bottom of the LPR.
Noid--While the LP hose is disconnected, ONE or TWO (depending on amount of time passed since last lubing) drops directly into the LP hose. Screw LPR back on and re-attach LP hose.
Ram--One drop onto each of the ram's o-rings. Spread by finger, just like with the bolt.
After reassembling, air up the marker. Remove the barrel. Turn the eyes off and fire 10-20 shots without paint. Your marker should now be sufficiently lubricated and ready to own, pwn, mow, rock, and any other terms you can think of!
If anyone has any other methods they use, or things they do differently, feel free to add them. I believe Inflicted does his basically the same, but I think he uses Dow or comparable grease on the ram.
