We did a quick test with some spare Wickes black oil based outdoor wood paint. It seems to have good coverage on even one coat. The Ronseal took 4 coats for something just about passable, but not great.
Pic is over a knot.
Drying time is the only pain.
I'm tempted to do a first coat thinned down with thinners to help with penetration to help with colour longevity. OH thinks that's a waste of time and we should just slap it on. Ultimately it should end up 80% covered with plants.

I've painted green oil based eggshell (f&B) on fence panels in the past and they stayed green. 2 coats but black might take more. I've used a dark grey primer before with some success.
If you just slap it on you'll probably be fine.
