DiamondFinish Clear Aerosol in the Gloss Sheen is the shiniest and offers the most reflection. It is remarkably similar to a mirror-like finish. To get technical, it is between 90-95% gloss measured at a 60-degree angle.
DiamondFinish Clear Aerosol in the Satin Sheen is not as shiny but does have some shine. To get technical, it is between 45-55% gloss measured at a 60-degree angle.
With that in mind, of Gloss and Satin, Satin would offer less amount of reflection and Gloss would offer the most amount of reflection.
