Goobersan and typical2, for what its worth on the auto glitter, its like spraying a car, it works best if you spray a light clear base coat, let it tack, spray the glitter(usually mica), let it tack, then spray a clear top coat. This will give nice depth and help the particles lay flat, giving maximum effect. Looking at how the glitter oriented itself in lines, it looks like some of it may have settled in rough sanding grooves. Hope that helps.
