Any of you guys use something like this?

What is the benefit or perceived benefit?

I was thinking I might make a vinyl cover for my mill to keep dust and other
shop particle out of the slide surfaces and screws to reduce abrasive wear
and increase the life of my machine. Now I am wondering if an enclosure
might be better. As I type I am thinking also that it might reduce working
noise while running a CNC program. I've got a sewing machine and a welder
on standby. LOL.
