I have never done this before, but am afraid if cutting oil gets all over the fresh cast, I will have difficulty getting it back out. I was thinking instead, wash them down with laquer thinner out of the gun, epoxy prime, and then do my machine work. Then at least oil couldn"t penetrate other areas. Any thoughts? How do they do it at the factory? Thanks Josh [Reply]   [No Email]

Maybe this is my answer. Josh [Reply]  [No Email]

All the cast I have worked on is saturated with oil anyway from leaks. [Reply]  [No Email]
