Almost forgot. I need to make a correction to a statement I made in an earlier post.
I said Evaporust will not etch good metal, but only removes rust from rusted metal. I was wrong.
Evaporust will definitely etch good metal if left for too long in the solution. I found that out when I left the nose of my spindle soaking overnight. Temps were in the high 20s and low 30s in my shop (only a wood stove for heat). Evaporust works best when warm, but works even when cold, just takes longer. I left the spindle soaking overnight. When I pulled it out of the solution it left a dark line where the surface of the solution was. I figured it was just sludge, but when I cleaned it off with 0000 steel wool, I could still feel the line with my fingernail. I few strokes with some fine emery took it off, but it was definitely an etched line. So, just a word of caution.
