krylon makes a nice clear uv-resistant spray coating which can be found at your local art store near the painting supplies or at a walmart near spray paints and stuffs. be liberal with it (meaning spray the shit out of it since graphite is really fine dust, but not to where it's dripping wet). do it outside and don't breathe in the fumes or it will coat your nose hairs and throat with acrylic for a few days.
