I agree with bigred, just mask up everything but the black and spray the black parts in one then unmask the rest as you go.
You can spray the silver on top of the white fine (make sure you have a good coating of white so you can't see through it.
If you really cant do it that way then you could back the white with silver and then re-apply the black on the bottom half where necessary.
You are causing more problems and higher risk of getting it wrong this way though. If you choose to do it this way you need to make sure you can't see through the white backed with silver at all otherwise the black may show through.
Good luck.
And do option 1 as bigred says if possible.
