[QUOTE=samlar;2706687]Got new radiator yesterday and installed the old one was still not leaking pepper seems to work[/QUOTE]
Yeah presumably it fills any small holes like most other temporary fixes.
Pepper could well be a good one though as it might expand after it’s lodged in the hole.
On that basis I’d guess that very finely ground stuff wouldn’t work quite as well.
I doubt that any chefs could advise further on this though!
