Can the 5 ft. Galvanized Metal Mobilehome Rockface Skirting Panel be used inside the home on interior walls?

Yes.

For interior wall installation, consider the nails over adhesive, this way if you decided to remove them at some point you will only have nail holes to spackle over. If using as a wainscoting and it will be resting on the floor or baseboard and you could use carpet tape on the lower edge and the top trim could be installed just over the tope edge of the panels to hold them in place. Many creative ideas.
