The tilly project(s) are looking excellent. When it comes time to solder the gal. iron petrol tank, I think they use a flux called 'killed spirits' its a mix of diluted hydrochloric acid and pure zinc. Some people make their own, buy the acid from a hardware store and a lump of zinc. There was a tank sealant called RED KOTE or similar , you mixed it with acetone , it might be available still. Mike
