Yep, used it to seat motors, lead sheet ballast etc. When you want to remove anything held in place with it, get some dental floss, the waxed cord type rather than plastic tape is better, start at one end and floss away.
Be aware if you use bathroom sealant on flat, high gloss or waxed surfaces, it may not hold heavy items. WD40 is supposed to be good at removing any excess on yer fingers only then you have to have a good wash of the hands to get rid of the WD40 smell!
