Let's say that I have an air compressor that I have not really treated with lots of TLC. Let's say that I've had it for about 15 years and have only drained the moisture inside the tank a few times. Now let's say that it's rusting inside.
What eventually happens? Does the rust eventually eat through and the tank begins to leak, politely letting me know it's time to buy another? Does it blow up and take down everything within a one mile radius?
Just wondering on an academic level. Certainly none of this is accurate in my particular circumstance. Nope. I'm sure my compressor loves me. I'm just a curious guy.
