The new Montana RUST Effect spray now available - for the illusion of rust and oxidization. Ideal for hobby, DIY, or creative projects. Apply as a single color, or both together as desired for an organic look. Can be used on different surfaces such as paper, cardboard, primed canvas, wood, glass, metal, ceramics, porcelain, stone, acrylic, and other paintable materials. The rust effect is created by a nitro-combi formulation that mimics the appearance of oxidized. Apply RUST Effect Brown, and Brown Orange on top of each other for a more organic appearance. Rust Effect can be top coated and combined with Montana GOLD, Montana ACRYLIC markers, and customary acrylic paints once completely dry. Pre-priming is required for application on polystyrene (Use Montana Styrofoam primer and make sure to seal the surface completely). Details: Brown 13.5 oz.
