I like very thin coats, so three is my magic number. The first will be super sheer! The second builds really beautifully! Third a great thin finish! If you don’t like very thin coats, then two regular will give you full opacity as well. That is what most of the swatches reported to me. Finally, my quick-dry formula is still in play with these! No trips to Polish Mountain and they are quick to dry! What else could you want?
