    Use of J-B Weld on Aluminum Frames?

    does anyone have any experience with the use of J-B Weld or J-B Kwik for repairs to cracked welds on aluminum frames? I am exploring options for my poor old dual-suspension, which, due to its age, the manufacturer is not going to honor a warranty replacement for the frame. Is it safe to use in high-tension/flexure/torsion zones? Has anyone out there attempted to do this to their frame? If so, how was the outcome/finished product? I have also been checking into some local mom-and-pop welding shops who can do tig-welding to see if they'd be willing to grind out the cracked welds, prep the surfaces, and re-weld the spots that are no good. Any opinions out there?

    I would take the frame to the best race car chassis builder that wasn't too far away, and have the damaged areas TIG welded.

    Yeah, then they have to re-heat-treat the frame.

    OP - no, I would NEVER EVER EVER use it on a frame.

    Unless you really live up to the "No Fear" mantra and don't fear faceplanting when that frame fails catastrophically.

    Just replace the frame.
