Yes I appreciate your experience and that is why I am asking. What do you mean by mess.
As with everything there's PTFE and there's PTFE, it's main application is as a pipe seal white water, yellow gas, green for O2 and I think there's a few others for specific applications. It's designed to fit and forget pretty much i.e. not being undone at regular intervals.
The most common is white, when used on sump bolts it turns into a stringy oil soaked mess, depending on how much is put on (most over do it) half is left in the sump thread, the reminder spread on the bolt or strings off it, as said a mess. If you don't mind all that, happy days.
The real point is if the sump blot is leaking something is wrong, my advice fix it properly, wrapping PTFE around it is a bodge, one which often doesn't work.
