On the topic of correct surface prep.... I have a 1960s engine with magnesium castings that I want to clean (blast?) and have an anti corrosion surface treatment applied. Originally this was a DOW chemicals dichromate passivation that is specific to magnesium castings. Does anyone know a way to do this or a company that does this in Auckland? Datlow - your comment about not dipping Ferrari magnesium wheels in acid wash comes to mind.

How's that magnesium cam cover holding up to scuffing and repainting? I have an older engine with magnesium castings and was told they would continue corroding even after painting unless re-passivated.
