This does exactly what it says it does, and it’s super cheap. I’ve only used it for brazing plain steel with brass and bronze, but I don’t have many doubts that it would work on the other metals it claims to. I mainly use it hot-rodding style, but it seems like it would make a usable paste if that application was preferable.For anyone looking for tips on best results, I would say don’t skimp on product when hot-rodding, let a decent amount clump onto your filler rod, and in turn use your torch to let that melt onto the entire part your brazing, and don’t be afraid to add a little more if you’re noticing any flow problems. If you’ve added enough flux, the brass should come flowing fairly quickly after the flux melts into the joint. I’d also recommend having a container of water nearby; quenching the piece you’re working on will help any flux coatings fall or chip right off.
