Re: [CAD_CAM_EDM_DRO] Stoddard solvent for EDM?

I'm working on an EDM project for another gentleman and he forbids me to use
anything other than Rustlick EDM-30. This is for lower voltage work - for
higher voltage work, I think they have a 250 version. You should be able to
pick this up at a tool supply company.
