VINYLUX is a breakthrough polish that lasts for 7 days! There is no need for a base coat as it will negate the performance since the adhesives are already in the color coat. The patent pending technology works with natural light to create an enduring, long-lasting polish. While ordinary polishes deteriorate over time, VINYLUX dries naturally to a flawless finish and strengthens its resistance to chip over time.
