Lifter galley paint
I sandblasted this cast iron intake clean, and filled the cleaned out pits with JB weld. I used Akzo Noble 10P42-NF on it. This is that fluid resistant epoxy primer. MEK and paint stripper wont touch it. Only way to get it off is to grind it off. A friend of mine has a super flow engine dyno he bought used. Previous owner never drained it after use and all the water passages has corrosion. We sandblasted and coated all the water passages in it with this stuff. 6 years later he took it apart to inspect it. Everything was still coated and corrosion free. Not so sure I would use it on an engine block unless I could bead blast all the surfaces that I would coat with it. I figure it's good enough for the water passages.
