These Loctite 221 or 222 are great for the countersunk screws, also great for locking fuel taps in the tank when you want certain orientation, difficult with typical seals. Grub screws will be sealed with same Loctites, no problem to undo. I use them a lot, only rarely normal strength for external screws, well, it depends and you have to think a bit before applying.
Yes, multiplate clutch, but I will try to have low force springs there, ATF in primary and semi-dry clutch, only a few holes into clutch cover for oil mist. I´ll see, takes till next year I guess.
