hough I have already painted some of the Epic Forgeworld Ork Gunwagons, I am currently painting some more.
They started with a white undercoat and then I sprayed the bottom with black paint to seal in the resin.
These are very detailed models and well worth getting and very good value (compared to the metal models from GW) at £5 for three.
I also like the weapons on them and it is worth getting them I think just to get the guns for conversions.
