Which "loctite blue"? The liquid stuff? The paste or the gel?
I've found that the gel works best. It stays a bit gummy and seems to hold better when it does finally cure due to it filling the threads so well. But it doesn't hold like the red stuff.
I have to use the red loctite on my T-Maxx CVDs. That Picco .26 would loosen them up 2-3 times a gallon at least until I went with the red. Sure they are a PITA to get out but they don't come out on their own anymore which is a good trade off.
