Have a radiator with a small but noticeable shallow dent in it.
I was going to just swap it out as I'm about to redecorate the room anyway,
but since the radiator is a bit big (about 8 feet wide) hefty, and in
otherwise good condition, I wondered if anyone has any success in using some
sort of filler on one?
I suppose it would need to be a flexible filler a bit like the stuff used on
car bodywork, but don't know if/how it would cope with the temperature
