For anyone that plans on wet sanding their plaster pool in the future, I found a really nice polisher on Amazon (Amazon.com) that I just started using recently. It's so much better than the one I was previously using that didn't have a hose hookup, ground prong, or variable speed options. This new one I bought is adjustable speed, takes up to 5" pads, has a built in GFCI on the cord, is pretty light weight (compared to others I used), and has a nice water flow regulator and hookup for your garden hose to keep the pads nice and wet. The splash guard is helpful to push all the water and the Crud removed off the plaster in the direction you want it to go for easier cleanup. Also been using these pads (diamond cut 50 grit and 100 grit) as well with good success -- https://www.amazon.com/dp/B083R4SMY1?psc=1&ref=ppx_yo2ov_dt_b_product_details

Definitely get wayyy better life on the pads with this wet polisher, instead of using a dry one and having to manually control the water with a separate garden hose. Seems like I'm getting 4x the life on pads now versus the older setup.

The combination really does a great job at removing winter's calcium crystals and last 20 months of calcium carbonate staining from calcium hyrodixide coming out of the fresh new plaster that has built up, along with smoothing out the plaster for a nice feel to the touch. Also finding that maybe the best thing I purchased was waders to keep me completely nice and dry/warm even while doing in 40 degree weather outside without any sun, I should have picked those up a few years ago.

Anyways... power sanding sure wears you out and leaves you pretty sore after 4-5 hours of use (wear eye protection too or tiny flecks of stuff will get into your eyes!), but the results are amazing. Big thanks to @onBalance for the tips along the way -- his knowledge is amazing and he's a huge asset to TFP. Over 90% done now and getting ready to fill, hopefully on Monday.
 
How much time has the power sanding of the pool taken?
 
Well, its two of us.... both with the same polishers. It's hard to say cause we're not keeping track of the time but I'd wager 18 hours between the two of us so far.? But that's a very rough guess,

That makes sense. I have watched a crew of 3 or 4 men sand a pool in a day.
