I prefer using super glue to epoxy because it allows me to align and clamp a crack before applying any glue. It is very thin and sucks right down into the cracks and bands very well to bakelite. Plus if you use the baking soda trick sets up instantly. The result is a very tight, strong repair.

With epoxy you need to apply to both surfaces and then try to fit them together. Alternately, you can fit it tightly together and rough up the backside (even cut some groves to give the epoxy something to bond well to) and slop the glue on the backside.

I've had trouble with Bondo outgassing in the past and causing bumps in the paint.
