Sorry I don?t have any shots of the layout and in fact this shot was taken on first trip to the lake and I was not happy with the motor too powerful so will fit gear of some kind and the electronic speed controller is being changed too.
As for the rust and dirt my method is a little free hand and no exact colour.
Items you need - Humbrol 82 Matt Orange, Humbrol 33 Matt black, fine brush, new bottle of thinners, kitchen roll, a CD cover and two steel nails.
Ok put the nails in water and leave outside for few weeks till nice and rusty.
I paint the dirt first after what your to paint has been drying for at least a week, take the black and brush, and fold up a piece of kitchen towel until its about 20-30mm at the end then soak with clean thinners with the brush dab on a small brush load once and in light vertical strokes with the kitchen towel wipe off till just a vertical smudge remains and repeat over whole boat (but remember don?t leave too much dirt effect on, if after the boat is finished you think it needs more that?s easy to do but you cant take it off easy if you think its too much).
Now for the rust bring in the nails and let them dry and when ready to paint wet one I try to get the mixed paint tone (not colour) to about 75% to the dry tone, that is a little darker than the dry nail
Take the CD cover and put 4-6 drops of orange on it and fill the brush with black and mix in (only a little black needed). now apply where you want the rust, spots, vertical along a plating seam horizontal where ever you want and then rub off as with the dirt in vertical strokes till just a rust smudge remains and again remember it easy to add more later hard to remove too much. if you add a spot of dirt or rust and you think its in the wrong place as long as its wet you can remove it completely by keeping rubbing.
That?s about it just practice, look at pictures of real boats of type to judge how much to apply.
