The "toner" deck stain I use on my deck soaks very deeply into the wood
and does not peel, even though I treat only the exposed side of the
wood. My deck is a southern exposure and gets merciless sun and rain
and snow, and high foot traffic.

Stain doesn't peel. It wears/washes away. You could use a solid body
stain on your porch, but you'd still have lots of preparation to do.
