Ideas about how to keep the galvanized steel end bell assembly from corroding through?

I rent an apartment that came with a Badger 5 Insinkerator. Not long ago it jammed, and I had to take it out to have a look at the problem. Turns out a random screw had somehow fallen in (not related to the Badger). Anyhow, I removed the screw, but upon reinstallation I had a leak-- out the bottom of the disposal. I opened it up again and could see that the stray screw had punctured a hole in the end bell assembly. I cleaned up the hole with some steel wool, but as I was doing so I discovered that the entire end bell assembly had become paper thin all the way around. It was also clearly pocked with tiny craters all over its surface. Once I had it immaculately clean, I treated the assembly by covering it with a thin layer of aquarium silicone, which I then let cure before reinstalling. It is now holding water, but I dare not actually run it for fear the silicone will tear and the leak will return. Others have already asked about these kinds of leaks: it looks like the galvanized steel corrodes through after a few years. I am considering coating the top of the end bell assembly of the next garbage disposal with the same silicone before installation to prevent this from happening again. Is this a bad idea for any reason? Are there other suggestions for protecting the end bell assembly from corrosion? The zinc plating on the steel just isn't able to hold up (the stainless steel grinder, though... that thing seems to be immortal!).
