I am getting a new machine and moving some others and it is time to do something about an ongoing issue. My shop walls are painted drywall and they are coated with cutting oil and pieces of metal chips that stick to the oily mess. I was thinking of putting on the stuff you can get at Home Depot that is kind of like paneling, but is made out of 1/8" or so plastic. Not sure how well that stuff holds up or how easy it is to clean. Has anyone put anything similar on their walls that can comment? Stainless steel would be nice, but a bit on the expensive side.
