Have you tried Araldite or similar?
No, but I will try it.
...would like to hear how you will apply it inside the frame tube.
BTW is it on the seat-tube or down-tube? If it's on the down-tube making a special clamp from a jubilee clip may work to grip the riv-nut. Bear in mind that the wall thickness of the frame tubes and access with a drill makes your choice for brutality very limited. It's damn awful that even high end frames use these crappy 2p riv-nuts.
My intention, glue-wise, is to apply a tiny amount under the flange of the rivet.
It's the downtube, so the FD method wont work. The tubing is very thin at this point on the CAAD 9 frame, so it will be difficult to sort.
