I always lay down a coat, let it flash, then step back 1 foot and lay down a mist coat. That usually helps the flake stand up correctly. Sometimes you get "paint lines" in metallics even with great overlap. This comes from spraying too heavy or close to the body. What this does is puddles the metallic flakes and they all lay flat. Thus from certain angles there is no shimmer because all the flakes faces are pointing in the same direction. A mist coat partially flashes in mid air so that when the flakes hit the surface, they stand up and vary in reflection angles. Hope this helps.
