I haven't used any of the fancy stuff from anybody, but if the parts are clean and properly tightened, there should be no room for leaks.
I agree with Matt tho, the loctite name is being used as a specific product. Loktite makes MANY different types of "thread dressing" for many different applications. When I described using loctite on aluminum threads, I meant actual "red" thread locker. That is what is called out by CNC and Wilwood. On the brass fittings, I use liquid teflon paste from loctite.
