I just inherited responsibility for a small prototyping shop at my
office. The walls are very dirty around the milling machine. I'm
planning to get them repainted, and was wondering if it is worthwhile
to cover them with clear polycarbonate (or whatever) to make them
more washable.

Any cost-effective ideas or tips?

Thanks,

Stan

I've seen sheets of white 1/8" polypropolene used for that.
