Only one photo today --- here's what I did yesterday and today:
Yesterday, I spent a few hours doing the final scraping and sanding of the uke, using first 150 grit, and then 220 grit, sandpaper. Then I sprayed (with a Pre-Val sprayer) a coat of shellac (Zinsser Seal-Coat) on the top, waited till it dried a bit, and then covered the top with some paper & masking tape. I also taped up the fingerboard surface (such a tedious job!).
Then I put on the first coat of Z-poxy for the pore fill. I had these little tiny credit card-like things, so I used that, and, for the larger areas, I used a regular credit card (it wasn't actually a credit card, but an old fund-raising discount card I had lying around). One thing I found was that, if I curved the card as I scraped, it would conform better to the curved areas (such as the side bouts). Also, I actually did a lot of the sides with my gloved fingers, because it was easier to get it smooth that way on the curved sides.
This morning I level-sanded (not down to wood, though) the Z-poxy with some 320-grit sandpaper and put on another coat of the Z-poxy. There it sits now (to the right). I might, later tonight, see if I can level-sand this coat, and see whether or not I will need a third coat, to fully fill the pores. (Usually I do need three coats.)

Level-sanded the second coat, and put on a third coat of the Z-poxy. Will level-sand that one tomorrow.

Turns out I needed a fourth coat of the Z-poxy, to fully fill the pores. So, that's what I put on today.
