How to spray paint plastic? As an oil painter, working with acrylic paints and plastic materials is more or less new to me, too. First, the plastic must be cleaned with mineral spirits. A base coat spray paint for plastic is available, but I figured I didn't need it. A wide variety of colour topcoat spray paint for plastic is available, but I only needed black. I will also use Rust-oleum's Stone accents for the illusion of a roof shingle's surface.
One should wear wear a protective mask, gloves, and goggles when using spray paint. And the work area, well ventilated. My "well-ventilated" area is my unheated garage with its doors open. And, as spray paint works best when the temperature is above freezing, the uncooperative GTA cold weather, delayed my project's progress. But, hey, delayed progress? As the past owner of two new homes that were not ready on time, it's all in keeping to the spirit of building development.
I love using spray paint, and if I was a lot younger, my art path might have followed a different path. But after putting a fair bit of work into the research for my proposal, and discovering how building development affected the salmon in the Credit River, with hindsight, a project that uses fiberglass, spray paint, plastic, mineral spirits, electrical power, sandpaper and rags, is a contradiction to its intent.
