Crack in radiator

I just noticed a hairline crack in my radiator. I only noticed it because of the residue from evaporation. I haven't gotten low on coolant as of yet. Can I repair this with an apoxey and achieve good results?

apoxey wont work as good as epoxy

Best to apply epoxy inside of the side tank and you need to prep the surface clean and make sure its sanded and not smooth

If its a brass cap, no.
I even tried to silver solder it and had no luck after time because I couldn't get it hot enough while it was installed and the cap was on, even with it drained.

i have soldered many brass, copper, steel tanks with silver solder only

have to use blow torch or big 300 watt Weller solder gun (not sold in most stores) and put a strip over the crack or it will crack again
