Hello,would any one have experience of making the corrision less noticable on a case back
ie, so its not so black in appearance.
I have tried baking soda as suggested on the Web but made no differance
Many thanks

Isn’t this gunk from an old gasket?

There's certainly some pitting there, but there also could be gasket goo as well - I use 99% alcohol to clean up the old gaskets - works wonders.

For the pitting, the OP could try some vinegar or evapo-rust.

It's not trivial to repair pitting like that. Most people who do laser welding won't touch it.
