I'm far from a weldor, but I recall many years ago seeing a rod made by
Eutectic that was almost a perfect color match to gray iron. It was a torch
applied rod as I recall. Nickel rod has a distinct yellow cast and shows
up very well, so it is not a good choice if you prefer to not see repairs.
Pretty hard to match. There's a "cast-iron" paint available that
uses powdered iron as its pigment, and it works wonders. We used to
use it over cast iron repairs. Not to pass off junk on a customer,
just to make it cosmetically acceptable. The welded repair was
stronger than the original, especially in areas of thin sections that
broke easily and had to be built up with the weld. Never had anyone
bring one back.
The paint wouldn't work too well on surfaces under heavy use, of
Cast iron rod, flux and torch application. Many years ago the lifter
handle on my inlaws Franklin handle got broken. I welded it as above
and filed the top surface smooth. The weld was a bit proud on the
curved underside but I left that. After it "aged" a few weeks, you
couldn't see the repair on the top surface. This was in the '70s and I
still have a couple rods but I would imagine you could still find them
somewhere. Otherwise, just use a piece of CI from something broken.

And for flux? Can I use the same borax type flux I use for brazing? I have
been trying to find this answer for months. My welding supply dealer sent
me to a welding shop where "they know everything." Didn't get the answer.
As far as I know, you and Ernie are the only ones with any of this rod. So,
should I melt some CI into the V of a piece of angle iron to make my own
"Aufhauser RCI is a high-quality gray iron oxyacetylene welding rod, designed
for gas welding of cast iron, general fabrication or building up new or worn
on castings. RCI is excellent for cast iron fabrication, repair of foundry
filling in or building up new or worn castings. RCI produces machinable weld
that have the same color, composition and granular structure as the base metal
(gray iron). The weld, if properly made, can be as strong as the original
