I have several pounds of 3/32 rods that I got awhile ago unboxed. The only markings I see on them is 306. They are a light in color, almost white, with a green overcoat that is very lightly & unevenly applied. Kinda like sponged on if that makes sense. There is no rust or corrosion on the stinger end. I assume stainless but can't find any info anywhere. My Hobart book shows 308 as the lowest ss stick rod. Anybody have a clue as to what they are?
