Lettering Pinstripe Enamels are an oil-based paint that are resistant to acid rain and UV Rays. Featuring intense pantone colors that are easily mixed or blended, they dry to a great gloss finish. Alphanamel can be reduced using Alphasol Reducers, VM & P Naptha, or High Quality Turps. While Mineral Spirits is great as a cleaning solvent, it is not recommended as a reducer. For brush or roller application only. Use on metal, wood, leather, glass, acetate, brick or stone.
