The cornerboards on my house are made of 5/4 X 6 lumber. I have
replaced 3 of them with redwood and have no problem with those but the

any synthetics that would work. I didnt see anything that Trex had
that would do the job.

There are composite ones now. There are also cedar which is pretty
good at rot resistance. Pine will last longer if you prime it
completely, extra on the ends, before install and make sure it is
caulked properly. The biggest problem is that most of us wait till
our house really needs caulk/paint before we do it. I just replaced
some corner boards and window trim myself before I had the painters
come. At $3k or so a pop I procrastinate on the painting. Worse on
my lake house, it's stained and I only got 7 years out of the last
job. House and detached garage were $5 to do. No wonder I put it
off, haha.
