Montana Cans GOLD Fluorescent color range radiates brilliant fluorescent colors by day and glows warmly by night under UV light. Easy and clean application is achieved by the low pressure valve system as with the whole Montana GOLD range. For best results, apply fluorescent colors to a pre-primed, dry white surface to increase luminosity and improve coverage. Due to their synthetic orientations, fluorescent colors in general do not have the same opacity, light fastness and longevity as normal high pigmented colors.
