Hi guys,

What have you found to make rough cast aluminum (i.e. Cobra oil pan, Cobra valve covers, Cobra intake manifold) look like show car new again?

Mine are good, but I know they could be better with the right product. They just don't have that uniform gray color they should have.

I've tried some acid based mag wheel cleaner, and that helped, but it didn't completely work.

What do you use?

Thanks for your time,
John Thomas
