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.
Yeah I did polish it with a fine scotch pad.
I don't really care what it looks like, I'm just worried it may not have enough wax on as it looks like pictures I've seen when boards need a wax, (white areas along the edges). I don't want to damage my board as I'm off for a week soon and won't really have a chance to redo the wax.
