I was taught that high heat opens the "pores" of the pan a little wider to help seal tighter when it cools down trapping whatever material you are seasoning with.
I have never tried the bees wax method, I just use oil and salt, grind it in when good and hot, let it cool then wipe clean. Works, and has worked for years for me.
I cook almost exclusively with cast iron at home and camping, and really do not have to re-season that often, I always dry my pans over heat/burner and wipe my pans down with a light oil film after they are dry.

I fear the day that technology will surpass our human interaction, the world will have a generation of idiot's.
