DIY Aluminum Radiator Repair

Who had repaired an aluminum radiator themselves and what did you use? Epoxy or low temp (MAP) welding/soldering are my options but need some input from anyone who’s attempted to repair things themselves. Muggy Weld 1 looks promising but pricey (but I would buy if it’s as good as promoted) and the Harbor Freight stuff has good reviews. Various epoxies might do the trick. Anyone?
