Hi Hammer, yes I did and I didn't it appears use a completely air tight box either. I can get any of the foil off with some elbow grease so I don't think that has done too much damage.

I can't get nitric acid here as an individual and frankly I don't fancy playing with that stuff. I could try the rust remover but I'm not sure that will work will it? it's more like a hard but removable serface. If I gently tap the surface it comes off like a crust.
