When I started using Deft, I didn't put enough on so it dried with a rough matte finish that would not buff out. It had to be sanded smooth and coated again....and again.... and again as I learned. Then I put too much on and it would create drips and sags, causing more sanding.
When I spun the lathe too slow, too much finish landed in one spot, causing a drip. When I spun it too fast, the piece would stir up the air so badly that a lot of the finish wouldn't even reach the piece. The finish that got there would frequently drip to toward the largest diameter as centrifugal force slung the finish outward. In both cases, you guessed it...... more sanding.
My technique ended up as: Aim several fairly bright lights at the piece because you want to watch for their reflection in the wet surface. Starting with a smooth surface, spin the lathe at around 200 rpm. Get the can 6 to 8" away from the piece and point it toward the bottom ring of the piece. Spray without moving the can, creating a ring of finish. When you start spraying, the surface will turn cloudy. Keep spraying just until the reflection of the light shows it turning glossy. The moment it turns glossy, QUIT! Move to the next ring up and repeat until you get to the other end. You want to overlap the finish just enough to keep a fully wet edge but don't get too much in one place.
Keeping a full wet but not drippy will minimize the sanding and buffing.
The good news is that it's hard to screw it up so badly that you can't sand it off and try again. I never created firewood because of an irrepairably botched finish.
Your mileage may vary, of course.
We do segmented turning, not because it is easy, but because it is hard.
