Crossed thread - how long before LS-X has water pressure on

[Makeitgo]

Hi All

I've just gone to swap out an old rad valve for a new one, and found a problem with the rad's thread (tail's thread looks in bad nick).

So, I tried to, ah hrm, re-cut it/reform it with a thing I found made of black steel and now I've tried the new tail in the rad's thread and it's better than a hole in the head now.

I've used a fair amount of PTFE tape on the tail thread and put a bit of LS-X near the outside end of thread for for good measure. Has anyone used LS-X and then exposed it to water before the 2 hours Fernox specify?
Thanks

Leave it as long as it needs to, to make sure it does its job properly

Impatient, huh kiljoy. I thought I might get away with half an hour or something. But seriously, thanks mate, I needed you to pull me up.
Yup, no heating or hot water tonight then... My wife will say it's OK we'll boil up some water and have a bath that way, but I know what she'll really thinking, oh yes I know : -)
