I am building a Westland Wyven and have painted the main colours using revell enamel sky matt 59 and humbrol enamel 96 (dark grey blue) can anyone please advise what would be the best colour to mark the panel lines and weather the bird in especially the sky colour. Many thanks.

Hi Chris,
There are many ways to approach this but I use artist oil paint and "real" turpintine for panel line washes and I apply the decals, or now, I paint on the markings first using "Miracle Masks" I will then give the model a couple of coats of hand brushed Klear, to protect the painted surface. For a wash on "Sky" I find that Davey Grey is an excellant choice, this is a browny grey and compliments the Sky perfectly. I also use tint spots of neat Davey Grey, applied with a cocktail stick, and "dragged" back with a finger, paint brush or cotton bud, to simulate oil staining and other detail staining. For the Dark upper surface, Extra Dark Sea Grey I would start with Burnt Umber or Burnt Sienna and add a little black to it. On a WWII RAF aircraft with Dark Green and Dark Earth Camo I would, for the upper surfaces, start with Davey Grey and add Burnt Sienna or Umber or maybe Madder brown.
Another possibility for your upper surfaces is to try Paynes Grey, this is a Blue Grey, again it may require darkening but it is worth a try om it's own first.
I would always stear clear of straight black
HTH.

I agree with Mal, stay away from black, I think the davy's grey for the underside, unfortunately i have onle been able to get the alkyd type which dries to quickly (but i'm still experimenting) as for the EDSG paynes grey work really well with out darkinging just check out my Buccaneer I'm currently doing Link to item. I use paynes grey most of the time and it works for most colours as can be seen on my Skyraider Link to Item.

Hope this helps
