what kind of nails were used if galvanized or stainless were used they shouldn't be rusting . post a picture

Actually, although galvanized nails might not "rust," the zinc in galvanized nails reacts chemically with cedar and can cause staining. I have always used stainless nails and had no problems, but these are expensive and people often skimp and go with galvanized. For nails that are already installed, there is no fix short of replacement. I'd try to live with your situation, and wouldn't bother to replace them...unless the installer used ordinary nails, in which case, the stains will be very significant.

I will live with it and touch up stain as needed
