Looking to make an awning. Lots of cruisers use pvc water pipe - it
ages in the sun and breaks - but it's cheap.

Friends have an awning that uses the bendy fiberglass tent pole
supports - like glass fishing rod stuff. They disconnect with ferrules
so are easy to stow - but all the ones they've seen have plated steel
ferrules - they rust and stain the awning.

Any better ideas?
