I watched that video and looked around but no one here (Canada) seems to sell it. Was not willing to order it as it would take a long time to get most likely.If you view the Polyvance video, it shows making some major repairs, then testing at working temp afterward. What did concern me is that their process involves heating to a fairly tight range, melting and adding material like welding. The result is quite impressive but if I were to try, I’d like to try on a test sample first. Finding a junk radiator should not be hard as Denso supplies to Toyota, Honda, Ford, Caterpillar, and others.
