So here goes, I'm sure you've all seen the infomercials where someone uses a propane torch and some special rod and basically solders aluminum together, miracle aluminum repair where its stronger than aluminum. Have any of you tried any of the products, and if so would you recommend them? I've seen quite a few which mostly seem to be the same stuff, Alumi-weld, Alumarod, Durafix, Muggy weld alloy 1 + 5, Alumi-pro, kirkweld, HTS-2000, and I'm sure the list goes on, ranging from 15-60 bucks a pound. Do any of these work, and would you use them on non-critical applications such as, fixing boat leaks in a cheap old aluminum boat, adding simple brackets to aluminum bike frames, repairing dinged portions of outboard lower units. These sorts of odd jobs that are difficult to accomplish with welders due to the configuration and disassembly required.
