Take a look at this site:

and skip down to "The Final Touch" heading.

Unfortunately, Russ died a few months ago. *I was surprised to see his

A final polish with swirl remover a week after letting the
shellac cure saves you the spiriting off step and won't
burn through due to momentarily not paying attention.
