Engine cases...

[Trolleywire]

Hi there,

I have another question........ engine case polishing. The cases on my '80 550L are rough looking and seem a bit corroded. How can I make them look new again?

Thanks.

first you will need to remove the plasticote finish the factory put on them the get some metal polish and buff them into the shine you want then recote them for ease of maintenance. Or once you have old coating removed you can paint to your liking

Find a bead blasting cabinet. Use bead blasting media, not sand. I think it's called glass oxide. It will make them look new. Polishing cases would be a real pain.

I think his were like mine that they were polished from the factory then given a plasticote. the coating has chipped away and left the aluminum in bad disarray.
