I've just done my first wavy camo, using blue-tac. Not bad, in places, but those tight turns can be difficult, and I also didn't press down hard enough in places. Plus, I filled the spaces with Maskol, but it seems in places the paint made it way through, so I guess I didn't put the Maskol down well enough in places.
Also...(and can anyone advice here), sometimes around the edges of the bits I was painting the brown (1/72 Airfix BoB Spit camo colours), was darker. Not spraying right?
Thanks for your technique Arbarne, think I'll try it with my next wavy camo job (a 1/72 Airfix MiG-23 in Libyan colours, radome, underneath, plus 3 more on top, 5 colours in all!).
