Hi, I just completed sandblasting a frame from a 72 c10 and where the rear coil springs mount to the frame there is some rust through. I thought I could just build the few holes with some weld but what I thought was metal is not. Does anyone know what this filler material is between the frame and spring perch, a magnet will stick to it and it's very brittle. I've repaired the holes by welding a 1/8th thick plate over the spring perch but I'm now concerned about this filler material that is falling out, hope I'm making sense.
