In paint technology, the sheen is the glossiness of a paint finish. Glossy paints are shiny and reflect most light in the specular (mirror-like) direction, while on flat paints most of the light diffuses in a range of angles. Gloss can be measured as a percentage. Carver Auto wants to use paints with over 85% gloss. Interpret SprayGo Red #5123 has 85% sheen with a margin of error of 3.5% This means SprayGo Red #5123 could have as little as Question Blank 1 of 2% or as much as Question Blank 2 of 2% gloss.
