Is RG45 the most generic/general purpose fill rod that can be used on boring low-carbon steels like A36 or rebar?

I'd be using oxy-acetylene. Just want something real plain for patching up what's basically scrap steel. I last used ER70s on real thin wire and sheets, but that was a while ago.

Any specific real-life reasons to pick one over the other for non-critical uses?

I welded a lot of stuff with an OA rig and a clothes hanger when I was younger. Its not really a big deal for A36 or other mild steel. Rebar is less consistent as to carbon content so who knows. As you say non critical so if it sticks it sticks.
