I just got mine, I use the glue pot. I tried the brush and the silicone applicator, the brush is very stiff, and becomes stiffer with glue on it. I'm going back to flat bristle brushes. I'll give the silicone applicator another try, but wasn't impressed so far. I use a hair dryer to speed the process, the Aquilim 315 dries much slower than a contact cement like Tanner's Bond. The Aquilim is much more forgiving to misalignment, I can pull it apart within reason, the Tanner's bond pulls leather apart if you try to pull it after the two sides touch. The instructions say if using on leather, to apply to one side and press together, if using on other surfaces, apply to both sides and wait until it goes clear. I did a lining for a checkbook cover the first way, then used the both sides/go clear method when putting the pockets on the lined cover. The second method worked much better for me, I'd like to hear what others have experienced.
