Red locktite on freeze plugs?

I have always used plain old silicone on freeze plug, unit my last motor. Could not get it to seal up. Even used one of them rubber plugs, but would not seal up. was Dumb Enough, to put stop leak in it, to get to a race. still leaked when eng cooled down. Even started a thread on here and everyone keep saying permatex 1 or 2 and that was with a vary pitted rusty hole. Been a year now and no problems.

I learn my lesson. cost me pulling my motor, an hour or two of flushing out the block and replacing all the freeze plug,(to get all the stop leak out) Been sealed tight as a drum ever sence!
here is the thread if you want to read it. The vary first post shows the pitted hole.
Pitted freeze plug bore. How have you got them to seal?

yes, i said Freeze plug, and everyone on this form new exactly, what i meant, and got the right picture in there mind's eye! have no intent to change this in my vocabulary.
