I was just doing some smoothing yesterday. Backpanel of a dresser, so doesn't need to be be too pretty, but good opportunity to practise.
Thought I would give an update.
So, I had previously built up about 6 coats, sanded it flat with my ETS EC 125-3, 240 grit until fully flat, and then sprayed one final coat.
I waited a couple of weeks for the urethane to cure and then did final sanding and polishing.
I started at 1200 grit until everything was sanded flat, then 1500, then 2000 then 2000-wet then 3000-wet.
A lot of use of bristle brush vacuum attachment when dry sanding.
Close to edges was sanded by hand with a small sanding block.
I used mineral spirits for lubricant when wet sanding since it was water based poly.
Then Mirka Polarshine 10 then Mirka VF-5.
It polished up real quick. If you don't have a polisher, I bet you could readily polish it out with a yellow and black pad in your hand.
My first attempt at polishing is the back-panel, which you can read the reflection.
My second attempt at polishing is 5 drawer fronts, which you can see my light fixture has two different types of bulbs.
Very happy with the results.
