Two and a half weeks waiting, and day off means polishing time!
5 hours later...
It's come up much less black. Pretty happy with it though!
There's a few visible flaws, including a big one off the left of the image a bit where it looks like I sanded through the stain before TO and somehow didn't notice. It's where my forearm's gonna go though, so I'm sure it will look worn there eventually.
Feels nice and smooth, and looks kinda semi gloss which is where I wanted it.
Also I've glued the neck on and am now waiting again, this time in a fairly nervous state. 24 hours? 48?
