ya I was just gonna say to back up what Nanaki said go get yourself a rougher exterior surface roller not the thin interior wall ones, and the proper exterior brush to do this by hand, it's the only way to do it. 2 coats of will do the trick, just make sure to lay on your first coat very thick and cover every crevice and corner. I literally find myself stabbing with a brush the areas not easily reachable, lol

I've done a few full fence installs and finishes for my dad's company just like this over the years and this method never fails me.

And from the pictures you posted there honestly it shouldn't take long, I by myself have finished bigger fences than that with 2 coats in less than 2 days. The shitty part about this style fence is the mesh pattern at the top of the fence there, that shit will literally eat up almost half of your painting time, you're constantly having to touch up the paint runs because there's so many ways the paint can drip in and around that mesh.

But don't discourage yourself thinking it should take close to a week, just lay that thick first coat down that's the hard part, then the final coat will be a breeze.
