I am now at the stage where I want to weather proof my observatory roof.
Its
an octagon pyramid and I need to keep it as light as possible. Its made
of
6mm exterior ply and I am looking for off the shelf suggestions to
weatherproof it. I don't want to use varnish.

I have been wondering if I could use some kind of bitumen paint with the
fibres in, not sure what its called but its used to coat or mend flat
roofs.

Ron Johnson's ply dome that I designed at
http://home.freeuk.net/m.gavin/rondome.htm
is 'weathered' with flexible epoxy paint and after two years is still
perfect. It's much lighter than old fashioned bitumen.

I going to visit a chandlers next week and see what they offer.. I may take
my camping chair as well so I can sit down just before they quote the price.
Thanks
