Hi Steve,
Perf slip will only work on all combined tracks, so it won't help you much then, I'm afraid.
Usually, production sound mixers should compensate for the biggest delay differences (positions of mikes make a difference, for instance).
After that, sound editorial should normally line up the different mikes by sample.

On clappers, you can see that the timecode of all three mics is the same, but if you zoom WAY in, INSIDE the frame, one mic is behind the other two, though the clap is inside the same frame... all three mics were within four feet of each other. So, if I leave all three mics up in the mix, there's a weird "phasing" sound. Pull the one mic out and all sounds great.
