Check out http://www.trex.com/ as well as other composite decking materials.
Don't know about painting it, but I am sure the manufacturer would give you
some information.

I was considering making a somewhat intricate deck railing out of 2x2s
and was wondering what the best material and finish to use (I want the
final product white).

What type of wood/finish (or wood substitute if it's workable like wood)
would last? And would it need yearly re-painting?

I'm in a fairly dry, sunny climate.

Thanks in advance,

Rich
