OK The most likely cause of this effect is that you are holding the spraycan too far away from the spraying surface.
Give it another lite sand and remove the chalky appearance, clean up, then try wetting it up a bit more by holding it closer to the spraying surface, but dont be too heavy handed or you will get runs and/or sags.
Between coats allow plenty of time for the laquer to tack off ((touch dry) - gently use the back of your fingers to check for this, no unsitely fingerprints )
Practice on a bit of scrap first
