In using the JB Weld for plastic, I did take a wire wheel on the end of a dremel and "roughed up" the mating surfaces of the plastic parts I was joining. For now it seems to work but I have to agree, the primer and solvent approach sounds more effective.
That should work great.
If you ever have adhesion problems primers will save the day. After many years of working with plastics I find using a good primer is the main contributor to a professional long lasting bond.
Odd ball fact: the heat deflection tiles on the exterior of the Virgin Galactic spaceships are literally glued to the frame. Only primer and epoxy. No mechanical fasteners of any kind... adhesives have come a long way.
