I have the smallest weep of dampness on the bottom brass tank of the original radiator. It's been like this since I had the radiator recored 5 years ago. It doesn't drip or ever need coolant topping up it's that small, however it annoys me and I want to fix/replace it.

I've Googled Radweld type products and they seem to have a pretty poor reputation for clogging up waterways, particularly in old heater matrix. However I'm thinking such a slight weep (probably a 'not perfect' braze or something similar) that has got no worse over 5 years, could this be a perfectly good solution to the problem. Or do I bite the bullet and take out the radiator to either re-braze or replace?

Thanks Adrian@ and all the responses. Interesting feedback with a mix of good & not so good experiences.

I think I'll probably go down the safe route - remove, inspect & braze / replace. It's probably the only way to be sure I don't kick the can down the road for it to return at an inconvenient moment.
