Here's what Devy Epoxy Fortified Natural Pine looks like on western white pine. I paint all 6 sides of the battens (4-sides plus ends after cutting). On the smaller width boards (<8") I painted all four sides plus ends, on larger boards only did one coat on the center back of the boards.
For the Defy, Douglas-fir seems fine with two coats while the pine often seems to soak it in more so it needs three coats. I think it is a great finish, but only have a couple of years of experience with how long it lasts. Works best on horizontal surfaces since it is very runny. We try to paint most boards and logs/timbers before they are installed.
This shed is rough-sawn pine with a latex paint from Home Depot.
I would dry your wood as long as you can if you are going to use it green. The end product will be better if you use drier wood.
