I have my collection of ready-made washes (like Mig Brown Wash), which readily flow through capillary action. But now I am looking at my collection of streaking products (Rust Effects, Streaking Grime, Winter Streaking Grime, etc.), which do not readily flow when I try to use as a wash, but would like them to. I believe a thinning agent can induce my streaking products to behave like a wash. Has anyone diluted their streaking products and used them as washes, and if so, what type of thinner saw success? Thank you.
