I agree entirely. However, if the roughly painted, distemper finish of AEAF stripes is required, looking faded and worn, then use a similar sequence, but painting the white over the camouflage colours, as per the real aircraft, using one or two thin, patchy coats. This will allow a slight 'show through' of the tone of the colour(s) underneath, and extra wear and tear can be achieved by very small masks of 'Maskol', PVA or even grains of salt, sand or sugar.
