I'm making some weather deflectors for above my windows to deflect rain. Is there a grade of plywood which is suitable and readily obtainable? Thanks.

Hi morbius
You could try marine ply but it will need covering with a protective coating e.g. varnish or paint. You're probably better using upvc overboards.

Forget marine ply, It needs a lot of work to maintain.
Bite the bullet and buy Duraply very expensive but it lasts
