Thanks Evan
I nearly forgot, another material that can be successfully used as a wrap/dewshield is a light coloured foam yoga/camping mat. These are cheap and easy to cut as needed. I used one of these with my C8 - I found the mat during a council big rubbish chuck out
I painted the dewshield end of it with black paint. Served me well for many years. I couldn't extend the wrap further down the tube because of the forks, but it still performed really well without needing a cooling period.
Alex.
