I ordered three pairs of these panels.  Sadly, two of the six panel had rust spots from the grommets.  The kind man at customer service promptly ordered another set for me, to replace the defective panels.  They got here very quickly.  Unfortunately one of those panels also has rust stains on it.  I am still one panel short, and have not decided whether to get that one replaced or just live with it.  Customer service was great and the panels are nice, the way they were packaged seems to be where the problem lies.  One set was perfect, but one panel from each of the three other sets have rust stain defects.
