I've been using Shell DPL 862 for years and pump it out of a metal can. When it crystallizes I just put the can on a hot plate set on low for an hour or so and that takes care of it. In colder temps I will pump 862 into a paper mixing cup then nuke it for 5 seconds. Thats all it takes to give it water-like consistency.

As Steve notes above, in our shop we use Jeffco 1307/3176 mix from Aircraft Spruce. Yeah, if you want drum quantities of it you can probably replicate it from 862 or 832, or even 828 (the base resin for those stocks), with standard Epon diluents. But it's probably not cost effective unless you need lots, and some of the diluents are pretty nasty chemicals.

The MGS 285 or 335 system is nice because it carries the EASA/LBA stamp of approval, but the properties are about the same as the Jeffco.

[Edit add: Steve already hit all the high points]
