    I use J B Weld on them ,But any quality product thats A metal compatible type should work,Just check and see if its listed on the back for Radiators.

    ...and don't close the radiator cap, that way it won't build up pressure and blow out the epoxy!

    I consider epoxy a temporary fix, needs to get it soldered.

    Used the JB Weld, so far so good. Budget is too tight to seek outside service people. So far it fine even after a 7 mile run.
