What base does it have (water, aromatic solvent, catalytic)?  Elmer's is practically unobtanium over here, so I'll have to wait till my buddy's next trip to Trumpland .

Neoflight had mention this glue in latest build...
I have double glued in the past but very rarely. If it's something I need immediate hold, I'll use cyanoacrylate but try to avoid on joints that will need contouring. Like most, I find it annoying and the odour is a bit off but it does have its uses. For joints that will need sanding, can accept slow cure or I feel will need to bear strain or torque I'll use aliphatic resin glue. I've recently found a unique glue by Elmer's called "Elmer's Ultimate Glue" I like to use on high torque/weight bearing joints. I has a slight measure of elasticity but more rigid than Elmer's white glue. It is easily pruned or shaped with a pen knife or thin razor and sands/files well.
One thing I do is allocate a measurable amount of time shaping and fitting the joints. I will spend anywhere from a couple to 15min getting a proper fit. Building is relaxing for me and I don't mind taking it slow. It doesn't always mean I'll meet with success but at least I'm relaxed when I approach failure.
