Dave,
As Colin says try white glue (I used PVA from the local stationery shop) and not superglue. Use a small syringe with the end filed square and lots of practice on scrap.
The photographs are my rivets, before painting, on the engine room and boiler house in the Guardsman thread. Ok the model won't win the gold medal at the ME exhibition, but the effect of the rivets does add interest.
