This nmf discussion is the best on this post so far.I am watching for input. Black 12-
My own procedure would be as follows: Finish and prime as usual ,mix and match gloss,satin, flat blacks,blending as per the panel lines ,overall coverage ,perhaps the method mentioned above would fit in here and mask the black markings .(Cant wait to see the D-9 all in black)
This will be the base for the nmf which will also be various shades.All these coats must be left to dry ,between coats and after to ensure solvent dissipation.Then some good sealer coats ,I havent decided what clear to use ,these must be left to dry well.There is a lot of nmf on this plane so I would mask off and or liquid mask chips ,panels ,etc. Pre- painted items like landing gear ,fabric surfaces,etc. would be masked for all this as well.Some pre-shading may be in order at this point.
If I got that far ,and it was going ok ,I would then spray the 75 grays on the under wing and sides .My build has primer fabric surfaces, so they are already painted. Then the 84 green that is peculiar to this plane .And so forth with the 81/82 upper fuselage surface,lower surface nmf . Wing upper surface 75/77,lower surface 84/76 ,nmf geardoors. Then the peculiar patches all over this plane. Finish/seal with clear coats.
Writing a method out like this is helpful in 'seeing' the procedure .It also shows me this aint no picnic! I will add the step for the markings as in the above reply. (thanx bman!)I am thinkin' weathering would be a lot as it is depicted late war with crappy gas exhaust staining ,field splash , maintenance damage etc. Wash's and pigments for 1/24 scale would be ok I think.
