I got this rhino years ago in a joblot of battered vehicles and unfinished conversions that caught my eye. It was covered in mud-effects and patchily painted. I scrubbed off the mud effects, stripped the paint off it, added a space marine sticking his head out and a generic cannon that could be a counts-as for a storm bolter or even a predator cannon if I wanted. I then used a thinner mud effect to give it a bit of verisimilitude. I am quite pleased with this, it looks battle damaged but functioning, very Steel Guard-esque (Imperial Fists descendents with a touch of the Death Guard infantry slogger mentality).
