Sealing gas tank float

[Angelo Graham <a3graham@admmail.uwaterloo.ca>]

Hello List: 
Asked a question about the tank sending unit gasket earlier. Another
question along the same lines. 
Thought I could detect a bit of gas sloshing around my float when I removed
the sending unit. Any way to seal the float so it doesn't leak? Thought
about using some model plane "hot fuel proof dope" to seal the seams. Would
this work or is there some sort of epoxy magic out there for this type of
application?

Thanks again,
Angelo Graham
