Bilt Hamber auto-QD is highly concentrated and can be diluted up to 20:1 (water:product). However, for maximum benefit we recommend using it neat. For best results, lightly mist Bilt Hamber auto-QD over a panel at a time, and immediately wipe the area down to spread a thin, even film of product using either the supplied buffing towel or a PB Luxury Buffing Towel. Then refold your towel, and buff the panel down carefully to remove the film and reveal an intense streak-free shine.
