			Does anybody use  rust converters ( Rust-Oleum, Corroseal et al)? 
		
		
		
			It has tannin, that converts rust to black magnetite and a polymer to seal it completely? There is no way to de-rust examples like Bandook's katars without leaving only a foil-thin sliver of live steel. I have shown here a 15-16th century bauernwehr preserved like that. That's how the surface looks like  |
