    Remove the clouded Sight Glass.
    Order a Watch Crystal from XJ4Ever.
    ::( Convex Dome-shaped Crystals are available fm TimeSavers.com )::
    The New "Window" will be Crystal (Glass).

    "The Old School Method"
    Replacing Site Glasses with Watch Crystals
    by: Rick Massey
    All rights reserved.

    I mixed some regular 5-Minute Epoxy. I used the narrow ends of toothpicks (many) to place the small amount of epoxy behind the crystal. [It was more like a "smear" than it was a bead.]
    Keep it close to the Ridge so when you seat the Crystal it wont ooze behind the Glass.
    This foundation SEALS the Window.

    The outside sealing geta done by placing a partial drop of epoxy at the edge. Tossing the toothpick that was used to apply the epoxy and using --> many other toothpicks <-- (I had a half-dozen between my lips) to "drag along" the freshly mixed Epoxy taking advantage of its slow capillary action.

    I used a bunch of soda cans or 3X5 Cards and shot small amounts of UN-mixed epoxy on the concave bottom of the can or Card.
    Then, when the epoxy you are working with just begins to "Pull" ... discard that mix and blend yourself a fresh one of the UN-mixed ones you have lined-up.

    Once you have the sealing bead all around the new CRYSTAL ... take full advantage of it being crystal and shape the epoxy around the inside diameter of the window.

    Use your little finger moistened with "Good Old-Fashioned Spit" (saliva) to make a nice looking finish ... like a glazer would do on a window.

    Clean-up BOTH the Crystal AND the shape of the seal with lacquer thinner.
    Use old, cotton, T-shirt cloth and moisten the cloth stretched tightly about your finger. Closer to "Damp" than "Moist"

    The lacquer thinner will clean the glass off anywhere you might have goofed while simultaneously helping you apply a really fine-looking bevel on the epoxy around the glass.

    If it isn't crystal or glass and you touch it with lacquer thinner; you'll be back to Square One, immediately.
