Paint — combination primer and top-coat?

user-958947 | Posted in General Questions on

Paints are now offered in a combination primer / top-coat in one can.

What’s the science behind this? More resin or pigment or both?

Is there a downside to using this vs. the traditional primer and then top coat later?
