Cracked radiator - Radweld?

[wreckxxx]

I've got a small crack in my radiator (speedbump damage) and coolant is very very slowly dripping out (one drop per day onto garage floor).

Damage is months old and the coolant level seems barely to have changed.

Doesn't seem worth spending £hundreds on a replacement radiator at this point.

Has anyone tried Radweld? Good/bad experience?

dont bother with radweld use k-seal a lot better

Thanks - is this stuff ok to use on an RS4 B5? i.e. no narrow sections in the cooling system that could get clogged?

not sure on the technical side of things!
very popular in old and new cars

i wouldn't put rad weld or k seal in my car, get a new rad and be safe
