How do you build 22 bleeding shocks

[Moose]

Really interested in how you build the shocks with the option bleeding caps (or stock sct caps)


I use the black O rings and a similar to green slime grease for all the seals.
I fill them up, let all bubbles escape, pull down the shaft, screw on the cap, push in the shaft, close the bleeding screw. I end up with 1-2 mm rebound but very much "negative rebound" when I pull out the shaft. After few runs I get more and more rebound while driving.
When I build the shock with some air in it (push in shaft to bleed but pull out and than screw down the bleeding screw, move it several times and than bleed it again) it is better but still not perfect and I wonder if thats the way to do.
