No top white? It sounds like you are double hitting your base so you don't have to have a top white, but that means a thick base and stickiness is definitely likely.
Curious how you like Legacy as an underbase? If you were impressed or not and what white do you prefer is not Legacy. Have a gallon and going to try it as underbase next week. Thanks!
