I've been finishing up a couple of projects, including adding exterior trim to a tool shed. The trim on the shed is 1x3 and 1x4 pine. Because some inadequately prepped painting on the property didn't hold up very long, I'm being much more diligent about this. I'm priming all bare wood with oil based exterior primer before covering with a compatible water based exterior paint. There isn't a lot of trim on this small building, so it wouldn't take me a much extra time to overdo it if that would make a difference. Would there be any benefit to priming, or priming and painting, the surfaces of the trim that won't be exposed to the weather? I'm not thinking in terms of deterioration so much as warping and checking.
