The only Loctite product that I've used is Loctite 660 - used it a few years back to solve a creaking issue at the BB when honking up gradual grades - put a small amount on each surface of a Chorus tapered BB bearing where the cups slide on , letting it cure overnight - was at the recommendation of a friend and great bike mechanic - worked wonders and solved the issue - personally wouldn't mess with Loctite willy nilly .
