What I found that works for me: ROS & 3M pad for rough work. I swap to 320 then 600 wet/dry sandpaper for hand sanding with WD40 as lubrication. I will use denatured alcohol to clean off the top then wax later as I still have the miter slots to work on next time. I was smart :) Cut a 55 plastic gallon trash bag in 1/2 and laid ontop of my new work table.

Ready to start hand sanding:
99% completion of top. Swirl marks and a couple deep scratches exist which will probably remain. Miter slots to do next:
