A major issue with this stuff is the propensity to use too much. A nice continuous bead about 1/4" is about right. This and a slight smear around any stud holes so there's no voids.
I believe the major reason for nuts backing off may be excess material leading to the pan moving slightly or vibrating, etc.
I also pull all the studs, clean them with brake cleaner and put them back so you nut them on nice clean dry studs.
This is what I've learned in working with this stuff on cars and high vibration vintage motorcycles.

The studs were new and clean. I used Permetex Hi-Tack between the gaskets and windage tray, and then a bead of Right Stuff between the gasket/pan, and gasket/block, probably about an 1/8" bead, and around all bolt holes. I can get a torque wrench on all the studs but one, and tightened to 90 in-lb, which is 7.5 ft-lb. That *should* be good, and I don't want to distort the pan. Do you think I need a bit more torque?
