The Montana EFFECT Sprays are a range of special effect sprays that include glitter, UV and glow in the dark effect sprays. GLITTER spray adds a silver sparkle finish to any surface. UV light paint is able to be applied on almost any surface. The colorless and semi-gloss paint is not visible in sunlight, but illuminates when exposed to UV light with a glowing, blue-purple color. The assortment is rounded out with NIGHT GLOW, the perfect glow in the dark effect spray.
