[Isimmo]

I can't remember the stuff I used (without going down the garage), but I inadvertently stuffed a Stanley knife blade into a rad whilst bearing wire, it pee'd fluid even when the pump wasn't running. Whacked some similar stuff over it and packed out the fins to an area about the size of an old 50p piece...

Promised I'd change the rad as soon as possible... Car was destroyed by local youth 8 months later and over 3000 miles, without loosing a mm from the header bottle max line...
