Guys
I have a 15 year old air compressor with a large vertical tank. While it is in good condition, I am a little nervous whenever I pressurize it that it might have rusted and the cylinder will blow.
As a test, you could take a new tank, grind the bottom thinner to simulate rusting then pressurize the tank to 200 PSI. I wonder if the explosion (yes we're talking explosion) would be dangerous or just a poof.

by the way, great job with the show.

Regards
Larry
