Experimenting on a base with GW's new "Barbed Bracken" and "Creeping Vines" kits.
Great stuff, but the paint doesn't spread and adhere well on the plastic which is softer than the usual GW plastic.
You can bend the vines using a hair drier. That's what I did, so I glued the vines unprimed. But then it was quite difficult to make the white paint stick to the plastic.
My advice is:
1. Wash the plastic with soap.
2. Bend the vines with a hair drier
4. Glue and paint.
