@Setanta,
There's hardly ever only one way to skin a cat or stop a leak.
Yes, set, I love working with pros. Especially those who seem to relish their work. They are the curious ones. They ask what the difference is amongst the four kinds of white caulk on the shelf because they want to know.
AND they report back what works, whether it's J-B Weld or PC-11.

When it comes to stopping that vessel, tub, sink, from leaking.
That's always good.
When I hire someone, and I do often when it's electrical, I ask if I can watch them work. Half the time, not always, but often enough, they like showing me what they are doing.
It might have something to do with the fact that I refer work to them when I can, but there is something to be said for sharing.
