Stuck some ally body panels and cappings on my project with Tiger Seal, as well as brass->marine ply and ally->ply etc. Tested it before, stuck really well. e.g. the wood would rip before the glop.
Used HTS2000 before (similar to Lumiweld), worked really well. On thin bits it could be a bit close to melting the bits. Durafix looks good and more versatile, but not seen it used yet. JB Weld is solid/no flex, if that matters.
