<VV> Leaky float repair

[Doug Mackintosh]

Hey gang! I have a leaking Rochester float. One boom is sloshing. When I submerge it in hot water it makes a bubble. 
 
I thought I had read recently how to get the liquid out and then seal these leaks, but I've looked everywhere I could think of and can't find it. Does anyone have a technique, or know where it has already been documented?  
 
Thanks
