I haven't done a lot of resin kits, but have used resin parts on my kits. Unlike others here, my luck with CA glues hasn't been that great. The stuff either sets up too quickly, or not fast enough, and almost always gets too old to use sitting in the bottle. The epoxy has a lot longer shelf life, and usually sets in the prescribed time. I usually use it for, as Don indicated, clear parts I do NOT want coming off, and for small parts that I want to stay put (antennas, handles, and other small pointy fiddly-bits that I'd like to not have to re-attach to the kit.
It's great stuff, I love it. You do have a fair amount of waste, but the bottles are so big, in relation to what you use, they last a long time.
