A question for the "yankees"...surface rust

[Scott Forman]

I'm a southerner, and around here we are not used to seeing much rust
on the underside of our vehicles. My newly acquired PT, however, was a
northern coach, and the underpinnings have surface rust on them. Since
this is all foreign to me, I ask...is this really something to worry
much about? Is there anything I should do about it? Nothing looks
weak or rusted through with holes or anything like that, there's just a
coating on everything under there.

The good news is that the body is fine, the coach was stripped to the
bare metal and re-painted 3 years ago, and I have pictures of it
stripped showing no body rust.

Opinions/advice?
