Having made such lining errors (not really improving due to anno
domini), I have had resort to heavy weathering although I always try
to maintain a variety of degrees from light to total.   My source is
the cellulose thinners wash pot which with the aid of the addition of
extra matt black from tie to time produces a realistic finish. The
degree is dependent on the number of passes. Water leaks are provided
with the addition of some white/ light grey in the spray pot.

Equally, my inability to easily obtain Humbrol No3 (Brunswick Green)
and having to substitute No76 (Uniform Green) is compensa
