I’m using food sage mineral oil to handle the sealing, though I plan on getting some pure Tung oil at some point to take over that job, I’ve seen some videos where it seems to resist temperature better.
And honestly I think these pieces were from when I built the rack for my gas cans, but it really could’ve been anything lol. I tend to hold on to any piece 2ft or longer lol.
I have never heard of…Meranti, was it?
