Magnetizing the Mechanicum Onager Dunecrawler

I have been knee deep in finals, but I have found a way to magnetize the Onager in about 30 minute to give you 3 of the 4 variants, I could have done all 4 but I didn't need to.  It's a great model.

Air Defense Variant

Anti-Tank

The trick is using a good bit of green stuff to bury rare dart magnets in the three sections.  that support the gums, I also shaved down the lump on the gun ring and then magnetized it and the 3 different gun systems.  Painted photo coming soon.  Dark Mechanicum of course!
