Thanks!, most all my weathering is done with artist oils, This was a mix of washes and feathering out the oil paint. And oil paint dry brushing on the hoses/wires, I start by clearcoating my painted parts, then just cover the part in black oil paint unthinned, then wipe off most of it, what's left gets blended around with a soft brush, Each layer sealed with duplicolor clearcoat then when done with it I spray dullcote. Washes are added last, Also in some places I brushed on some future to make it glossy like wet oil leaking, also when the future is still wet I applied some black pastel dust on it to add some gunk to the oil leaks
