Mop, EEE, Hard Shellac question

Im trying to get a mirror like finish on a guitar. Ive let the Hard Shellac harden for a month now but there are still a streaky bits from my efforts. Question, can I go very gently with a Swansdown mop charged with EEE? I would be using a drill and assume there is a risk of cutting through the shellac entirely.

Thanks in advance,

Sebastiaan

I'd try the EEE by hand first, and follow up with some wax. You can use the swansdown mop on the wax if you want.
