I once read about bentonite post secondary as a clearing agent. In my mind, using it early on in kit winemaking, it's just another tool to speed up the process. Bentonite is little more than clay with a (negative?) charge that aids in clearing proteins from the wine thus acting as a fining agent.
Your kit probably came with another fining agent/s to use post fermentation like chitosan or super clear. Did you add something like that at the k meta stage? Regardless, as SPAF suggested, you're on target for a fine mid winter drinker.
