I have recently a purchased 10 year old mobile home with a galvanized sheet
metal roof. There are a few patches of rust on the south side north is
fine. Question is what kind of preparation do I need to do on the patches
before using a roof coating or can I just paint over the patches. Also I
was told that it is not a good idea to walk on a mobile home roof like you
can on a regular house roof. Is this correct?
