I would like to apply a 1×2 pine molding (simply decorative profile, flat top) to the lower part of a 1×8 pre-primed fascia board, to add some detail to the front of my porch. What is the best way to adhere the trim, since it will not be flashed but subject to moisture? I plan to sand off the primer. Is waterproof glue and galvy finish nails good enough? Epoxy? Gorilla Glue? The finish will be oil primed and covered in latex paint. Any suggestions would be great.

Insurance industry research shows that stout roofs, strong windows, and metal connectors can help protect houses from high wind, hail, and hurricanes.

Screws. Caulk the joint and paint.

Not a wise choice, IMO, since it will try to trap moisture and cause rot. Ed is in a dry climate so he might get away with that there. here, I would first try to avoid it, and then, If I had to do it, would use Titebond II and SS nails and then caulk at the top edge and paint immediately if not sooner. I would NOT sand off the factory preprime.

For all we know, he's in Arizona :) I was thinking screws (or at least no adhesive) so that it could be replaced in the future.

When it needs replacement, the facia will be gone too, though.

I think you can easily do this if you use a little ingenuity and are willingly to perhaps change your initial design a bit if necessary. Your best options for design will likely depend on the style of the house, whether the soffit is closed, what material it's made of and whether you have gutters or not.
The point here is to prevent water infiltration that can't readily dry out. If you're floating the piece with spacers you'll have to add more spacers if your width gets wider to help prevent cupping.
If floating the piece under the gutter, try to size the gap small enough (3/8" ?) that wasps won't try to use it to build nests and bats won't move in. We've used ½" gaps for this and haven't had a problem. At ¾", it might be too encouraging.
Edit: If you use the floating approach, you'll have to spray paint up in there in the future to get coverage.
Knowledge is power, but only if applied in a timely fashion.

Stainless nails. Don't sand off the primer. Caulk and paint right away. Keep a good coat of paint and a good caulk joint going. Projecting out it is likely to catch rain and snow. It may well decay before the facia. If it's epoxied or glued replacing it will s##k. Oh yeah. Hit the backside with some primer or paint before it goes up.
Thanks for the advice. On second thought I seem to like the fascia as is!
And forget the flat top too. Needs a slope to shed water, not hold it.
