In this photo you can see the brown paint that was covering most of the wood. Due to its thickness, I had to use my angle grinder with a sandpaper flapwheel (36 grit) to remove. So, even though I don't have a planer, I kind of planed every single piece, by hand with my angle grinder. As you would expect, this led to creative solutions to various square/level problems. Additionally, it turns out after grinding off the paint, not all the pieces were pine. I think (but am definitely guessing) that the others were fir.
