Yoo betcha.

Well, you can still use the rivets, but you can then seal the rivets.   
Chris Difani turned me on to a wonderful product originally developed for 
Rolls-Royce turbine (jet) engines, called Hylomar.   It's a UK-made product that 
has a distribution company in the USA:

It's available on Amazon, cheep cheep.   Since the top of the tank surface 
may be a bit irregular, the rubber gasket often doesn't seal as tight as you 
would like.   In practice, after cleaning everything, put a generous bead 
of this stuff on both sides of your rubber gasket, lay the gasket in place, 
lay the metal ring atop it, let it set up for a bit (as much as it sets up), 
then rivet it to the tank, which may cause excess stuff to smush out.   Use 
some of that excess to seal the top of the rivets, and you're done. :>)
