I injected my motor mounts today, but needless to say it ended up being a little more difficult then orginally intended.
I started injecting the mounts and noticed that I was almost at the end of the tube and was only done with one mount. So I instantly figured out that the little pushy thing on the chaulk gun was FU(K3D up! So I took the tube out of the chaulk gun to find that the pusher at the bottom of the window weld turn sideways and the stuff was just oozing behind it.
Not having another chaulk gun, I just decided that I would pack them like you do wheel bearings, so I just started fishing the stuff out with my fingers. Needless to say it got messy. FAST. Eventually I had to get a kitchen knife to get to the part of the tube that I couldn't get with my fingers. That didn't work all the way either, so I just cut the tube open and had a ball.
Now my hands are semi-clean, and the mounts are filled and hardening as we speak. I had my wife take a few snaps with my phone, so they aren't the greatest but they show the insanity. Enjoy, I will update you on there progress and how they are once installed!
Taking the mounts out...Thanks to lpa1984 for letting me borrowing his mounts while mine are down

In the process of packing them with my fingers (Bad Idea)

All done packin'

Waiting for my hands to dry so I could peel of the window weld
