I saw an info-mercial about this stuff alumaloy, it's basically a high temp solder. It's a zinc alloy that can supposedly bond to all kinds of metal, and be stronger than aluminum. I was wondering if anybody had ever tried it, or it's competitor alumiweld? It looked as if it would be perfect for using for porting an intake manifold. It has a melting point of 730 degrees F, and supposedly is non-reactive. Thoughts?
