I use cheap craft paint, water, and a couple drops of dish soap.
I keep 3 on hand. One is straight black, another is mostly raw umber with a little black in it, and the last is raw umber with tan(leaves a dusty look…kinda!)
It does take a little bit of trial-n-error to get the paint/water ratio…I usually start with maybe 10% paint…if that’s too much, just dump a little out and add more water…not enough, dump a little out and add more paint.
Just like Fermis wrote! I’d just like to add one bit - some people (including me!) have had good results mixing some future into the mix - not much, like 10 to 20%. It also enhances the flow, but then again the dish soap is also intended to do that. Just experiment a bit and see what works best for you - I hope it helps, good luck with your builds and have a nice day
I see that as not being a problem when the wash is applied and just left to dry, and that is that.
When I do a panel line wash though, I blob some on the wing…rub it around with my finger, let dry, then wipe away the excess with a damp cloth, leaving the wash only in the panel lines. Would the Future make this application much harder to wipe away the excess? Or is it diluted enough, that it’s not an issue?
