Exhaust Rust

[Tourettes]

I'm having a bit of trouble with rust on the stainless steel rear section of the exhaust on my touring. It's been parked up for a few months in a garage and I have noticed a small drip of condensation coming off the bottom of the exhaust. Anyone ever experience this problem before or have any advice on how to eliminate it. This is the first car I've had with a stainless steel section and its never happened on cars which had standard exhausts on them that were parked up.

also stainless rusts if its been welded normally not stainless welding and if it comes into contact with mild steel.
