SV Quick Finish is just a spray detailer, does not have long term protection but more of a shine and light dust remover...maybe few days of "durability" but similar to many QDs but is great in that it just works and works well..little is needed and finish is spot on. Swissvax Nano Express is a top crack product and is like a spray wax with decent durability on top of wax and gives a uber slick surface and great shine/depth/wetness to the waxed finish.
