Dow Corning 3140 RTV applied to seal pouch - Step One of Four
Notice the two holes - You can see the bullet bleed through one hole.  Looks like the factory makes mistakes too!

---

RTV spead over pouch leather using fingertip (Step 2)

---

Using tissue to remove excess RTV.  Hold pouch in one hand and use tissue in a circular motion

---

Wipe the pouch using a circular motion until all shine is gone, then turn tissue to unused are and repeat.
I hold the pouch board in my Left hand, and the tissue in the right.  Sorry, but my right hand was holding
the camera in this picture. ALL excess RTV MUST be removed.

---

Nipple has been installed at this point, and with all openings sealed, and the nipple connected to a
bubble jar, you make sure that all is tight at this stage. I test using eight inches of water feeding
the bubble jar. This is my personal preference.

---

Bubble jar with open input. Look at the size of the bubbles (actually you cannot see the individual
bubbles, but this picture stops the action) and the froth at the top.  Lots of bubbles!

---

Bubble Jar attached to the nipple of the pouch.  See the one small bubble rising to the top.  The
bubble jar is testing the tighness of not only the pouch, but the pouch block as well.
