the comet had some areas that where redux bonded, i guess the technology was sharp in its day but mid eighties? it was crap and as a mech working on these a/c on any b check you would find bits coming apart so now its a case of simply riveting it back together
so i guess if you goggle redux it may help
oh i nearly forgot if you want to break a reduxed joint dump dry ice all over it - job done
