You have purchased the silver for the M3/M4 Taylormade 2018 clubs. This is a special paint which needs to be applied in this matter. Apply thin coats, brushing on a downward motion and then across the downward motion you applied. This removes the dark edges of the silver and blends in better. All silvers have dark and light metallic which only blends with brushing. It also removes the brush marks. This paint dries extremely fast, so if you don’t like what you have applied, you will need to remove fairly quickly with paint thinner before you start over. Shake well before using, but don’t worry about hearing the mixing balls for you probably won’t.
