It’s a clear, water like liquid sold in hobby stores for the assembly of plastic models. It is far superior to any other adhesive since it fuses the pieces together, the bond is as strong as the plastic itself. There is nothing better for 41 post and case repairs.

JB weld is great where you need to fill gaps but be aware that it can be slightly conductive. When you have repairs without gaps, or especially cracks, solvent welder gives a better result.

That will certainly seal it up quite permanently, but you're going to have quite a job on your hands if you ever need to open the module up again later. For stuff that's not supposed to open/separate, like cracked screw posts, I definitely agree though.
