They cannot even see the back of the shed unless they come
into my back yard. In fact, the overhang of the roof is on my property
line, but that does not bother me.

Seems to me they should be the one cleaning up their property, but
I know what you mean.

Looks like a situation that could start WW3 ) I would not paint it,
but the whole issue could be real complicated. Is it on your property?
If so, probably gives you more right to paint it, but then they might
someday own that little piece of land. If it is on the line, and a
permanent building, it might violate setback or easement requirements.
It may not be practical, but I think it would be better to plant a hedge
that hides it or add fencing to cross what is missing and paint to match
existing fence.
