I've used small pieces of cotten cloth coated in JB weld to get some jobs done. I've also used cloth with Fiberglass resin to do some similar support work. It was only a temporary patch or something that wouldn't hurt anything if it broke.
JB weld is awesome stuff. I've patched 2 aluminum radiator cores with it for our backup radiators for the race car and 1 large truck radiator that was on the dyno. JB weld doesn't work on header leaks where the air tube's crack just above the welds. Correction, they last approximately 1 day or 2 hours of driving and then it cracks and becomes too brittle.
