    I picked up a sheet of polycarbonate a while back to replace the windows
    in one of my milling machine enclosures. I know polycarbonate isn't as
    scratch resistant, but it is nearly shatter proof.

    Today I finally got around to replacing one of the six panels, and every
    time I walk into that machine room I am startled for a second thinking I
    left that door panel in the up position.

    I know it will get coated in chips, coolant, oil and scratches soon
    enough, but its kind of nice to stand there and see clearly the job
    running.

    I bought this polyester film to repair the insulating window inserts I made
    in the early 1980's, which have finally become brittle from UV. You could protect the polycarbonate with it. https://www.amazon.com/Grafix-Alternative-Templates-Protection-Transparencies/dp/B0015LWRZY/ref=sr_1_2?

    I was going to coat them with Dick Nite clear Coat, but then I decided I
    just wanted windows that aren't cracked or broken. (The originals are acrylic.) Most of the time I monitor the machine with the camera I put
    inside the enclosure anyway.
