Not just a regular detailing spray, it's a spray-on Graphene coating.
Shake well (important), then spray and wipe off immediately.
Must be applied in a shaded cool area.
Do not treat this like a quick detailer, treat it like a spray coating.
If the ambient temperature is toohotand streaking and shadowing start to occur, either use the coating again on the area and wipe off right away (it uses the solvents to take the high spots off), or use a damp towel to remove streaks then buff with a dry towel.
