Tom,
I understand corrosion very well, being a long time career mechanic and inspector, as well as former director of maintenance (several times).
Intergranular is internal to the metal, but is often found having surfaced, and may appear to be minor surface corrosion. Sometimes it's like chasing a gopher hole; a small amount on the surface becomes veins or areas beneath the surface, and an attempt to remove corrosion quickly leads to discovery of a very unairworthy panel or part.
