Aluminum Brazing Rods

Have any of you folks tried out the aluminum brazing/soldering rods like muggy weld? I think harbor freight makes something similar as well. Were you satisfied with them???

I'm trying to join a couple small pieces of 1/8" aluminum plate with a lap joint and don't have access to a tig welder. I've thought about epoxy like JB weld, but figured those brazing rods may work. What would you do?
