If you go to one of the shoots, that should be a very good test....and a good excuse for a thread.
FP-10 works quite well, and seems to stay in place about as well as Mobile 1 10-30, but not as well as TW-25B.
Any excess TW-25B that's applied to the rails ends up on the rear of the slide....not down the sides of the frame.
At this point in time, if I had a 500 round day ahead of me, I'd likely apply TW-25B once to the rails, rack the slide 10 or so times to distribute it thoroughly, then add some more.
