Barge also. I also have Tanner's and some Master contact cement. I primarily use the Barge, just because it's a bigger container, really. I put Vaseline on the threads to help the container stay sealed, and keep the lid from glueing to the container. I rarely use any clamps on leather. I've never been able to do it without leaving marks on the leather. I generally just put something heavy on top of leather to distribute the weight, but keep it pressed together if I am doing a clamshell sheath. I am generally doing pancake sheaths now though, which doesn't have the same issues at glue up.
