Sanding to 440 rather than just 220 grit helps but the real trick is getting
the area super clean before applying the finish.

Several vacuumings, Compressed air blowouts, tack cloth and closed windows
with still air all help.

After that, stir the finish slowly and avoid dipping the applicator in such
a way as to produce bubbles.

What is the secret to finishing hard wood floors and furniture to a
mirror like shine with glossy clear polyeurathane? I use a lamb wool
applicator but could never get the tiny bumps out.
