That is a first class shop..What is that wall surface made of that took the white paint as well as that?.I am going to guess that its sheetrock so I wonder how it held up 20 years, ever knock many holes in it?

In main machinery room of my shop I used a chipboard painted white which was cheap but was a horrible mistake in hindsight as it is rumply surface catching floating dust , has gone dark and isnt reflecting light as well as a good clean white painted walls should...I wishing I had smooth white walls and cieling....That lathe looks sweeet too by the way.
