Good overview ?

I'll probably want to refer to this info at later dates.

I do have a question about epoxy glue. I once tried the two-part epoxy for a kintsugi project and I found pressing down on the applicators very difficult to do even on a first try. Plus one side was more difficult than the other so the amount of two types of glue was different when mixed together. On a 2nd date, it was impossible to squeeze anything out and even my husband was unable to do so (despite lots of clean up w/ vaseline after the 1st try).  Have you heard of this happening or was it a "bad batch"?

I will rewatch this before I start a new project.
