Pacific Silver II is a light grey metallic polyester with a semi-gloss finish. Semi-Gloss: 37-70 Gloss Units Notes: A clear top coat is recommended for exterior use. While a clear top coat may improve UV resistance and the overall durability of the finish, it can occasionally change the appearance of the color it is being applied over. We recommend spraying a test panel before applying it to your project to ensure the final color meets your specifications.
