I noticed last night that the living room radiator is rusting through.
The rusty patch is at the top of the radiator, and at the back (which is why it has gone unnoticed, and it is an inch or so long by a half an inch high. It is just the tiniest bit damp to touch - so the actual penetration must be quite small and is just letting through a few drops of liquid.
It is quite an old radiator but I could really do without trying to replace it just at the moment.
Is there anything I can do to "patch it up", just to get me through the winter?
I was thinking about getting some of that "rust eater" stuff you can buy for cars that is supposed to seal the rust, and them slapping on a thick coat of hammerite or the like. Is this stupid or the way to go?
