Im restoring a '85 Grand National and my client is worried about the surface rust inside the door. Its not everywhere, in fact there is very little, but he wants it perfect (he's a rare breed). Im wondering if I sand and epoxy what I can reach and convert what I cant , would that be acceptable? If not what would? And any tricks on reaching those areas that are inaccessable would be appreciated. Thanks. Trevor from Gulf Breeze, Fl.
