I've been buying vintage tools for $1 each at this junk store and decided that now would be a good time to try the evaporust. It definitely works but boy is it slow compared to more agressive things like naval jelly and the evil wire wheel. I have to admit that I do enjoy the instant satisfactin obtained by the wire wheel! There are some tools that are so rusty and don't have any plating where I feel that the wire wheel is an appropriate tool.
