Chris,

Silicone sealant is designed to be used as a gasket.  Silicone will not
adhere well to either your fibreglass cabin top or the rail.  If you are
sure this is the source of the leak I would not hesitate to remove the rail
and re-bed it. Don Casey has written some definitive articles on re-bedding
and the appropriate bedding materials.
