What is the name of the clear stuff you put on your nails before putting the nail polish on?

I knw that you put something on before you put on tha colored nail polish. I actual nail polish is called nail enamel and the stuff you put on after that is the top coat. But what is the first clear stuff you put on?What is the name of the clear stuff you put on your nails before putting the nail polish on?
Base coat. It fills in any ridges and little imperfections that are in your nails before you apply the colored polish. Let it dry several minutes before you apply the color. Then, let your color dry too for several minutes. Then apply a light brushing of a top coat. Don't be in a hurry- take the time to dry each layer well.What is the name of the clear stuff you put on your nails before putting the nail polish on?
