I saw a TV add for a new product that supposedly makes welding (brazing actually, I guess) repairs to aluminum much easier; it's called ALUMALOY. It comes in rods, requires no flux of any kind, and only requires propane gas temperature. Almost seems too good to be true ... anyone out there have any experience with this stuff?
Same company also makes a similar product for steel and cast-iron; however, in these cases, a type of flux is required.
