Re: Cleaning up transmission case...
I just had reasonable success using Naval Jelly rust remover on an aluminum
part. This is a thick liquid containing phosphoric acid. I don't know how
comfortable I'd be using it on such an assembly, due to the risk of damage.
Its's think and doesn't run too much, but it is strong. I got a small
spot on a finger and it burned it immediately. Another possibility is an
aluminum cleaner such as Simichrome (sp?) and a stiff brush.
