Head Stud Sealer

I use Prematex #2 it is non hardening. My theory is that the non harding will flow to the area with least pressure (leak) vs hardening becoming ridged. As well hardening does not respond to heating and cooling....ie...expansion and contraction......my 2 cents.

Sounds reasonable. I just bought a tube of #2 to use on my 99A and was wondering what experience others have had using it.
