I have a project to rebuild a dozen park benches for my local Rotary club.

We're interested in replacing the redwood on the bench with recycled plastic
lumber. http://www.complexplastic.com/lumber...orce/INDEX.HTM

A requirement is to have each bench prominently labeled. The old redwood was
engraved and painted. Will that work on this material? Or would applying
vinyl sign material work well? Other options?

Engrave and paint it. Should mill nicely on any CNC mill. Could also hot
stamp it.
