One For The Plumbers
Central heating joint (nut) has a very slight seepage. When heat is not on a little water would seep and form at the top if the nut. When the heat is on it evaporates.
This is ok at the moment as I can see the joint but a new kitchen is going in and the joint will be behind the units.
Is there some sort of sealant spray that would stop this seep. I have tried to tighten the nut but seems at its tightest.

The simple way is to wait for the water to cool down... then unscrew the backnut... wind a few turns of PTFE tape around the olive ..... then screw back up. No need to be overtightened.
The best DIY method is to drain down (if it's on the heating circuit) or turn off the water if it's on the Hot Water side.

No, do not rely on sprays. You have to get into the gap between the metal fittings and make it smaller so that water cannot pass through, not stick something akin to a plaster on top.
Sometimes these joints do seal themselves as the salts in the hot water evaporating on the leak surface fill the gap I'm talking about but you can't rely on it.

Agree with all, no chance of a "spray-on" product working but their is another way if you don't fancy draining down e.t.c Fernox have a product called FP4 Leak-sealer which I have used a few times to good effect. Possibly another solution would be, if you're having "people" in to fit the new kitchen, ask their plumber to sort it for you for a few bob extra of course.
