I love looking at rusty objects and admiring the brilliant colors and textures that environmental elements create during the corrosion process. I've taken a lot of photos of rust and decay over the years, and am finally getting around to using them as direct reference for developing layered acrylic surfaces. I'm working on several of these surfaces right now as experiments, and thought I'd share my most recent one. I hesitate to share too much about the process, because the end goal of all of these experiments is to produce a self published book of weathered metal project ideas, but I can tell you that for this experiment I used a series of delicate acrylic skins (made from several different mediums, including Crackle Paste) embellished with Fluid Acrylic color, to simulate the look of crackled and weathered painted metal...
On my first try at this experiment, I worked from my photo on the right to get an idea of the colors and textures. The first finished sample is on the left, it is 4x4 inches in size.
A shot of the sample before adding the skins...I underpainted with Fluid Acrylics that I mixed to get a dark reddish hue. On the right is a very brittle acrylic "skin" that I made to simulate cracked paint layers.
This is a second sample, which turned out more how I'd envisioned the project. It still needs adjustments, but it's getting there!
