If it is responding to a resonant frequency from the silencer then how about dampening the source rather than the panel. Wrap the silencer?
However, if it is just a rattling bonnet vibrating against the bulkhead from engine vibration rather than a higher frequency resonance then surely it just needs more secure fastening at the bulkhead end to stop it rattling.
Try wedging a bit of material or spare rubber in there and see if it works then make permanent solution? Am not sure adding deadening sheet to the bonnet will stop a rattle unless you put it between the bits rattling and then its just a piece of 'rubber' anyway.

Enjoy yourself, it's later than you think!
