Erin, when you say, " . Body has very little rust....", and then let us know
that you're from Minneapolis,  I think that may be where the problem is.
The standard for "very little rust" in your neighborhood is, well, not any
gaping holes over 2 feet across or so.  At least this is my experience with
having lived in the area in the past and visiting there often.  Seriously,
this is a subjective thing, and lots of people are just horrified with what
we have to put up with here in the rust belt.

Rust on our Vanagons is usually seam rust, not structural, but it still
spoils the appearance and is hard to control.

Our condolences.
