Hi. For applying wax by hand and foam pad how much pressure need to be use? When using the Menzerna finishing glaze and Souveran carnauba wax to remove water spots the water spot is not remove. Then apply the Menzerna finishing glaze using pressure and rub it fast the water spot is remove. Are there anything before applying the Menzerna finishing glaze to fill the scratch and hide it with the filler? How much pressure is use to apply the finishing glaze and carnauba wax? Thanks.
