You're overthinking this. Just wax, scrape it down to the base and ride. It'll all need to be done again after a few days of riding anyways. Unless you're doing super slalom your wax doesn't have to be perfect.
The only thing I would add is a light polish with a fine scotch brite pad to smooth it out, but don't go ape shit with it...you'll take the wax out of the pores.
