Best product for sealing radiator cracks?

[g3org3y]

Hairline crack at the bottom of the rad which is only evident through leaking when engine is hot.

I was thinking perhaps trying some epoxy resin?

Only needs to be a temporary fix (few months).

Any other suggestions?

TIA

Depends what it's made from.

If it's plastic - replace ASAP - I've seen many then suddenly fail, taking the headgasket with them.
