For lace, you will not get an overnight hold using spirit gum. You apply it first thing in the morning and hope that the bond holds until you are ready to go to sleep that night. At least that was my experience. I used to carry some with me in case I needed a touch up after 12 hours or so.

With skin, I think you'll get an overnight hold for a night or maybe even 2.

Either way (lace or skin) the cleanup is much easier than using a white glue, ultrahold, or tape. You take a cotton ball and put some alcohol on it. You wipe your head once and your head is clean. No glue boogers. Compare a few seconds to clean your head vs. a few minutes with white glue. To clean the lace, just spritz some alcohol on the lace. But every now and then (maybe once a week), you need to soak the lace in some alcohol for a few minutes or use desolvit.
