New Idea but I don't know how to make it
I was just looking at some photos on some photographers website in a series called Beautiful Decay. I had looked at maybe two or three when I suddenly had an idea. I know some various ways of aging things, primarily metal, but there is one style of aging which must technically be possible but I am coming up with only a few possibilities as to how to do it on my own: flaking paint. So far I have thought of dabbing on paint thinner before spraying to make it have a weak bond to the surface or adding powder (probably whatever the surface is, just ground up) for the same effect and then with the weak bond simply sweeping over the area with a broom several times to flake the paint. These seem like they would be hard to make seem natural.
a second idea that kind of fits in is fake rust. By that I mean that the surface looks old and rusty (get your tetanus booster kind of thing) but is actually fully protected from the elements.
Any ideas you have are welcome and I thank you for them in advance.
