Lightly glue them to a section of discarded sprue and airbrush (or brush paint) them the interior color. When dry paint the exterior color(s). Finish as usual, and decal. Carefully pop them off the sprue holder, and...voila!
BOY, Who came up with the idea of making clear plastic planes??
And How do you paint them?? I getting ready to prime them, But, if I remember, I heard that you would paint them an interior color firs ( the whole plane? ) then paint the base color of the plane.
OH, I deal with 1/700 planes.
Thanks for your time.
