Minor rust under paint

[Gardner Yeaw]

Bruce,
I will give it the awl test, but it seems like surface. I can see,
however, that since it is below the emblem it probably started in the
holes used to mount it, and therefor could be deeper than I had hoped.

Ernie,
Yup, we talked about the tank already, I was interested in
differences between that and the galvanized metal.

Thanks
Gardner
