Industrial Rust Abstract Acrylic Painting

Industrial shabby-chic canvas art. Base layer of thick paste, into which some sprinkles of sand have been added. The whole surface has been blended into rough and ready abstract gritty surface texture. The surface has been allowed to dry and then overpainted with two layers of matt black acrylic paint. It is left to dry again before the following roughly applied layers of platinum white, orange, burnt umber, deep blue, sky blue and teal have been added, in a chaotic way, using sporadic brush strokes and sponging techniques. The overall effect should look like a battered metal panel, that has been left out in the rain to rust. There is large but barely discernible cargo lettering that reads "BUT IS IT ART?"
