hi
what you need is Macrolon which is avaliable from builders merchants, it
comes in large sheets and many different thicknesses. it is a sandwich of
Lexan ( polycarbonate ) and another plastic. It will not yellow or crack and
is said to be bullet proof. You can also cold fold it with a metal bender
without cracking so has many uses.

Looking for a source of Lexan or similar material that the supplier can
form
into a dome to be used as a lookout on my Open 40' singlehander. Radius is
21 cm.
Have tried various places and Google but to no avail.
Thanks in advance for any help and hints
