Now a character I know and some of may does not get on computors as he says they are a waste of time. His name Rusty Brown. He states that on silk, silkspan, nylon or any porous material you thin the dope to brushing consistancy. Dip the brush in the dope and make a pass over the covering one direction. He says do not, repeat do not go back over the dame area with nest strike of the brush. He says the second pass over the same area is what pushes the dope thru the weave. Takes time, but, it works.
