Today I have mixed feelings.

reversed the front shocks, feeling much happier about that now
bled the brakes, got the pedal rock hard, all seems good
bled the clutch, pedal feels good, can turn / non-turn the tailshaft as expected so it seems ok
filled the power steering
filled the cooling system.....and that's where we hit a speed bump.

The radiator has a 45 degree angle welded on to the bottom outlet, and the weld has a pinhole in it. Very small, it wasn't until some time after I had put in 5 litres of coolant and 8 litres of water that I noticed a very small puddle floor. It's giving about 1 drop per hour.

I reckon it could be tigged up in place, I would be able to get my tig torch in there but I only have scratch-start DC and I need an AC machine to do aluminium.

Otherwise does anyone have any experience or recomendations with the metal paste type stuff that is for stopping leaks? I'm not interested in putting a 'stop leak' type of thing into the coolant, but is there something that can be put on the outside to seal the pinhole? The welding option is preferred.

Don't even say take the radiator out, that is not happening.
