The reason was, I'd just replaced the radiator but then proceeded to stick a screw drive into as i attached the fan. It seals the leak VERY quickly, then goes on to seal others in future. Never had a problem with overheating or anything afterwards.
Thumbs up from me

radweld/barsleak usually lasted about 9months before it needed doing again. Had the waterpump changed during all this and there was no clogging on the pump or the thermostat.
I've used it on cars with slightly weeping core plugs and it's sealed it and they've never leaked again!!!!
Dont expect it to seal a massive leak, it wont.
Eggs do work as well, drop a whole egg in a cold engine and leave it running for 10 mins. Heater on if the matrix leaks, off if it doesn't. It'll generally seal a leak depending on the concentration of antifreeze you use. 25-35% it works, over that it wont work for long.
The idea is that these "bodges" only set solid in air leaks much like tyre sealant. They can be surprisingly good!

theres no job on a mk1 which is so hard as to requirte you to use radweld, just keep the system topped up till you can fix it. radiator - easy. matrix - easy. head swap -easy.
