Whats happening is you might be applying too much gloss white to cover the gray. A gloss color is "thinner" than a flat color due to the amount of thinner in the paint mix. Therefore, it could run or cause uneven aeras on the painted surface. What I find works is after the coat of gray primer, spray some flat white so it covers over the gray, then apply the gloss white so it gets an even shine/gloss. By doing this, you won't have to apply much of the glossy color to cover the gray primer because there is a surface that matches the color your applying over it. This works for gloss black over flat black, red over pink, sliver over black, and so on.
