Stic-tite aluminum radiator repair kit that I bought off of amazon. I used a butane torch and you just don’t want to burn the filler rod so try and heat base metal (radiator) before applying filler.
That won’t hold long should of pinched the holes shut at least to give it a chance but you handle that torch pretty good just weld it with Alina rod it’s aluminum. An is like solder then you won’t have it coming back in a month not knocking you just trying to help I did this. Shit for fifty years
