As mentioned previously, my Dart tank has developed another small weep, this time from the tap mounting point. And really, it's only a matter of time before it springs further leaks. In the absence of any metal tanks (unless someone has a spare one! If so, I'm all ears

It's risky, no question - as if it goes horribly wrong I'll have no tank at all, and no chance of a repair or replacement. But then again, it could be that I'm left with no alternative if the tank develops further leaks anyway! I'll probably have a go with the Loctite 3450 first, as a safer option, but if that doesn't work, I'll give it a whizz.
