Ork Wartrakk
I added some armour plates using plasticard, which I "distressed" with a craft knife.

I used some spare Imperial track to add some more armour.

Slices of plastic rod were then added as rivets to both the front...

...and the back.

I added some rivets to the frontal armour plate and used the searchlight from the Chaos Vehicle sprue.

I also drilled out the exhaust as well.

The next stage is the undercoat.
