It will probably never leak using that stuff but how do you get it apart later??
A buddy and I got talked into using that stuff in 1980 on the first engine I built.
We had to take the right angle adapter off and it was a nightmare. No one I know used it after that.
Thinking about it, I’m not sure why we even wanted that off the engine. There probably wasn’t a good reason back then but when you are that young you do things for bad or no reasons.
I just remember guys were not happy about that stuff.
