Oil-based 1-Shot Lettering Enamels are the professional sign painter's best value for lettering work. These vibrant, high-gloss colors spread evenly, leave no brush marks, and offer unbeatable coverage. They're also extremely durable and fade-resistant. The whites won't chalk or wash. Apply 1-Shot Lettering Enamels to interior or exterior surfaces including metal, glass, wood, and enamel-receptive vinyl. They may be tinted using 1-Shot Tinting (sold separately). Varnishing is unnecessary due to the high-gloss film. Paint is dry to handle in eight to 12 hours and cures in six to eight weeks.
