Thanks H !
Sorry Glenn, a stupid, dithery woman was in front of me at the check-out, b*ggering about with loose change etc !
So, a few minutes later than advertised, here's the pics of the mottling and white areas. The RLM 02 still looks very grey in the pics, but I can assure you it's the correct hue. I've noticed that one of my tungsten halogen desk lamps is pulsing, so this has no doubt affected the colour balance slightly.
Anyway, after careful study of the rather grainy photos of Schnabel's belly-landed kite, it appears that the light mottle, in a streaky, partly criss-crossed pattern, was either sprayed around the fuselage balkenkreuz, or the cross was masked, and the same with the swastikas on the fin. The area under the 'White 6' however, has mottle, which suggests that the number was possibly painted on after the mottle was applied.
Consequently, I applied some rough, cross-shaped masks to the fuselage, using Tamiya tape, and a square of masking tape to the each side of the fin, then very lightly marked the recognisable shapes and positions of the mottle pattern in pencil, using a thin stroke for each 'blotch', to the approximate size and shape, not something I normally do. The mottle was then sprayed free-hand.
The primed areas of the wing tips were masked inboard, and sprayed in Humbrol Matt White enamel, building up thin coats, but not too perfect, as I wanted to replicate the appearance of the distemper-type paint used for these I.D. markings.
Next step is to do some very light panel line work where appropriate, mainly around access hatches and control surfaces, and the first stages of weathering, before giving the model a gloss clear coat. I'm going to revert to gloss enamel varnish for this one, as I want a perfectly smooth, gloss surface for the home made decals, some of which will be very feint, and will need filling-in with acrylic paint afterwards.
Thanks again for our interest and support, and more soon.
