Re: Radweld?
 

I've used K-Seal in the pas to fix numerous problems, I can highly recommend it! Never had any adverse effects.

Re: Radweld?
 

in that case and depending on where its pizzing out, take radiator off sand the effected area and then use some 2 part liquid metal such as jb weld. do not use the one part stuff as its hopeless. leave the epoxy to cure overnight and don't sand down to make it look pretty.

Pattern part from Aaron radiators, 150 quid. One of the fan bolt holes was a little out, but not a problem.

Re: Radweld?
 

One of my family businesses was radiator repairers and builders.

If we ever got in a rad that had been subjected to sealants, we refused to attempt repairs as we could not guarantee the core would be free of leaks after our repair (undetected pin holes).

To repair, we would identify the faulty tubes by acid bath soak to clean then air/water testing, remove the tanks, solder closed the damaged tube at either end and then refit the tanks. Followed by pressure test, fin alignment and repaint.

Attempting to simply close the hole externally was a complete waste of time.
