Hi,

I'm looking at designing a sign and considering plywood backing or plywood letters. However, I'm not sure how to finish these signs for exterior. See link below for an example. Is this sign only going to look good a few years? How often would you need to replace it?

I do live in N. Utah (Ogden) and it's mostly a dry climate here, but very hot at times and sunny always during the summer.

Thanks and cheers,
