Loctite 5910 DOES stop it, done a few myself, it also sticks on arch extensions door mouldings etc etc etc, awsome stuff but expensive/ish.
It also works on deep sea goggles as mate used it, though he should have bought a new pair!!
I have also used it to stick on SUMPS with NO gasket as car was so old could not get any, I had to LEVER the sump off afterwards when I stuck it on my xr4i, then spend an hour straightening the sump!!
I have NEVER had a leak with this stuff ever from anywhere.
Worst bit is getting hold of it, as not many places stock it.
