JB Weld (I got mine from Amazon) is a great product. It's used to repair car parts and radiators. It sets hard, and you might need magic and diamonds to cut through it. Don't get it on your hands.
It's a 2-part epoxy, like green stuff, but much, much stronger. The rebuild took 3 days to finish, as I wanted each part to set and cure before adding higher-up weight to it. I haven't tested dropping the model, but I suspect it would hold...

Before I re-glued however, I took advantage of my clumsiness, and added details to the bits that even Heineken couldn't reach - oil stains, burn marks and scorching on the metal areas. There's a little OSL going on around the eye lenses, but for the most part it's a 'study in metal'. I've gone for T'au Sept - the white markings behind the head - so that it can fit with a standard-build sandy-coloured Tau army as a commander or centrepiece model.
Of course, I didn't get to show it off at Forgeworld's Open Day - the car wasn't fixed in time, and I couldn't get a courtesy car or rental, either. Shame. I would have liked to see it in the cabinet next to the winning figure (an Emperor's Children Contemptor was the victor by all accounts). My wife didn't paint her Tau Ground Crew, either. I'll do those guys next...
A bit of an anticlimax to the project, then - the model came out great - even with the drama of a faked reality TV show - but I didn't achieve the initial goal of getting it to the competition. Still, it's on CMON, so please vote if you think it's worth it.
And for anyone who's made it this far - I would gladly take on a Forgeworld battlesuit project as a commission. A real pleasure to build and paint. Just tweet me @minimodelpaint, and we can talk options.
