I had completely forgotten this trick; even with saving an article about it several years ago. I have 2 potted figs and am in the identical situation--zone 4/5 SE Wis. I think I will dab one and not the other and do a little trial. As I recall it was the use of olive oil only. I already begged hubbie to allow me to haul them into prime household space to finish off if they begin to look frost-threatened. After they finish bearing I'll shuttle them off to the garden shed where I have successfully overwintered them for 5 years. Always something fun to look forward to!
