Thanks everyone for the encouragement to continue this build
Since starting the project I've had no idea how to paint the camo, and have reviewed the book by Ray Rimmel which had a few helpful tips and tricks. Non of which I thought were easy. I ordered some Frisket masking film and went ahead with the paint work on the underside of the mid-upper wing...something that can't be seen much and a good place to experiment with techniques.
I made a colour copy of the WnW instruction sheet showing the pattern for the mid wing section at as close to 1/32 scale as I could calculate, and transferred the pattern to the Friket film over a piece of clear acetate. By making dots at the intersections of colour, I cut out four templates for each colour to be sprayed on after placing the film on a pane of glass.
By lining up the film for each colour, they were airbrushed on and then the inevitable gaps were re-masked with bits of tape and touched up. Very laborious, but it did the job. I repeated the process for the upper surface (mixing five different colours) and it went slightly quicker.
I think I now have an idea of how to do the fuselage, so hopefully light at the end of the tunnel. Hopefully my sequence of photos explain my process.
transfering the pattern to Friket film
the four masking templates for the lower side, sprayed a base colour
The upper side was based with ochre, and the first colour, mauve, has been airbrushed on.
The completed pattern on the underside - not perfect but acceptable
Upper side, again, not perfect but if you squint hard enough it'll work.
Cheers,
