What I have done in the past is melted all the oils, then left them overnight. By the next morning, the oils solidified again, but it was easier to whip them up without any lumps. If you have a lot of lumps that didn't get saponified, there is a chance that your soap might be lye heavy. Saran wrap over the top should be fine. If you use insulation and the soap gels, you will loose the trapped bubbles, which make this soap float.
