All those steps are overkill....
Using a nano or micro polish is like a glaze, then you're going to glaze it again for what reason??
With a
nano polish you will not remove much if any defects so you're wasting time with that, then glazing will fill in and hide some defects. Anything on top of the glaze will only last as long as the glaze which is about 2 washes.
If it were me, depending on the condition, I'd polish it with something more aggressive then finish down with the nano polish, skip the glaze, rewash it, seal it and nuba if you must.
