How to grease with Park Tool GG-1 gun

I am trying the new Park Tool GG-1 grease gun. You can have multiple guns and fill them with whatever you like. Such as poly lube 1000, anti-seize compound, carbon paste etc. Right away I like the heavy metal construction and black rubber seal located at the top. The park Tool Grease gun is easy to grip and operate. The GG-1 gets into tight spots to fill grease with whatever the amount you need.
