Gammera - sweet wiring job, looks perfect.
Eric- i have done allsorts. This is my first plane and first weathered NMF so it been a bit trial and error. There was no actual all over wash done.
Remember this is alclad not acrylic so any solvents i used may be the kiss of death to your plane!!
First thing i tried was chalk/pastels applied dry the alclad, no clearcoat. just put a bit on my finger and lightly brushed the plane in the direction of airflow along leading edge of the wings tail etc. make sure the chalk is properly ground or it will scratch the paint! Very easy to do too much (i did). then i used light grey pastels to dirty up the decals, the tail and spine and othe parts of the alclad. Next was thinned tamiya flat black sprayed lightly to blend in with the chalks, again i went too far. then shot it with alclad semi matt. this turned out too flat for a nmf.
The panel lines were originally done with grey chalks applied with a microbrush smoothed over with a dry finger to remove excess but with all the handling this entailled a lot of it had dissappeared by the time i had finished. the plane was then sealed with alclad light sheen which gave a much better look than the semi matt. By this time i had realised i had gone too far with the weathering so had to go back over bits with alclad, really low pressure really light coats! And respaying the tai/spine too. Then of course a lot of the pannel lines etc had to be redone (the never ending story). This time the were doe with faber castell brush tip PITT artist pens. they do a shades of grey pack and work beautifully for panel lines, dulling decals, small areas of grime going round the canopy frame to colouring in where the primer showed at the edges. these thing are great! Credit to Hawkeyes models for this. see linky. altough i didnot sand back the finish as suggested in the video due to the paint/clearcoat i used, i quickly removed excess with a wet finger or cotton swab.

i had worried about the decals looking "stuck on" to the weathered finish on the tail untill i saw this. If you zoom in the plane looks the same. result!.
