I really like the Light and Medium Rust Deposits, the Heavy was a little over powering for what I was working on. I tried using it along with AK Interactive Engine Grime Enamel, and it looked great. I applied it heavy over a model based with Vallejo Air Gun Metal, then after it had dried, I used a makeup sponge to wipe it away from the raised areas of the model for a really great looking rust effect that was very believable.
