No no no no.  most rtv is not gas proof and will dissolve.  Very bad idea

Dave- RTV (colour your choice).

Two suggested sequences depending on Cap design ( TR4 different from TR6s)
1- apply to top of of unit in trunk surround. Smooth off. Fill Recess in Cap-smooth off. Let cure overnight. Add more if required after both sides cure.

2- If bottom is flat  add RTV & smooth high, or if has Male surround just Add a layer on top.

On the Cap ( my TR4 has a gasket in a recess on the top flip of the cap) Add Extra high RTV.

Schmear engine oil on bottom part, Close top gently till catches.
RTV will cure and seal with a 'groove'. Problem resolved.
AlwYs easy to add Little more RTV as required.
