George,
Amazing! I "Googled" for seam rust and didn't get this site.
A picture truly is worth a thousand words...now I think I am sorry I was a
able to see what lurks behind those rusty seams! I think it would be
interesting to see others pics of the exterior rust and how it compares to
what actually lies behind as well.

Thanks!
