Polarising film
Does anyone know a supplier (in UK) of polarising film in sheet form?
I'm after a sheet about A4 in size from which to make a built-in
Polaroid sunstrip for my crash helmet. The idea is so that I do not
have to wear sunglasses and can, thus, look 'under' the strip if
necessary, i.e. when riding through tunnels etc.
TIA Richard
