Graceland Portable Buildings poor quality material Nationwide

The Graceland building came with parts of the inside wall peeled off.  It was thin sheets glued onto what looks like particle. board.

I went back to the sales guy, and he said that it's quality lumber.  But I had my doubts.  I can't believe that it passed inspection like that, with the particle board showing.

  And it was confirmed when I tried to paint the outside, and what looks like glued on thin sheets that had peeled off coul be seen.  rough material that didn't take the paint.

   They won't take it back, offered to fix the parts that can be seen, but the whole building is poor quality.
