Hereford Radiators efficiently sorted my RN radiator a few years ago. Header tank to core was leaking. They removed header and bottom tank from core, checked the core was clear and in good condition. Reassembled and charged around £100.
I hate unnecessary use of radiator sealers. Back in the day Jaguar used to recommend a dose of barsleak at services. The result was a build up of sediment in the bottom of the block which eroded the cylinder head studs which travel through the water jacket. One day a stud snapped in my XJ40 (horrible job getting the broken bit out) the rest of the studs looked like this.
Best to repair properly unless in the middle of a lengthy road tour.
