Hello all, First fully exterior project I need to do. Been asked to make a sign for a Condo Complex, the larger ones that go at the entrance. I was told they want to stay with "wood" since their last one lasted so long. I went to look at the sign, is not real wood probably Extira so looking to redo the sign the same.

Any suggestions of paint or finishing process for Extira for best longevity?

Or any reason I really should absolutely not go with Exitra?

Thanks!
