I definitely see not spending money on rare submerged lumber if you are painting black.
However, I do think there’s a case to be made for sourcing some old lumber of some sort.
The way most lumber is milled today, even if it’s “dry”…is pretty prone to cupping and twisting and what not. I do like the idea of tighter-ringed old wood that got all the warping and twisting out of its system….many decades ago.
