Hi,

What's the best wood and paint for outdoor signs exposed fully to the
elements? Best sealer after painting?

When I was in the biz, we used MDO, filled the edges with spackle then
primed them with alcohol base primer. Then painted the whole panel,
front and back with a foam roller using "Ronan" brand enamel.

surprised at the incredible finish you can get with a foam roller once
you get the hang of it.
