You should apply Gyeon Q² Booster in a dry place out of direct sunlight. For best results, it should be applied to a brand new quartz coating shortly after it has dried fully (i.e. at least 1 hour after the last layer of the coating was applied and buffed off). However, Gyeon Q² Booster may also be applied to previously applied coatings, as long as they are less than six weeks old and contaminant-free. In such cases, prepare the surfaces you are going to treat in the normal way (wash > decontaminate) and then do a wipe down with Gyeon Q²M Prep to ensure that they are spotlessly clean. In all cases, apply Gyeon Q² Booster as follows. Using the supplied dropping pipette, lightly wet one of the supplied Gyeon Q²M Applicator Suedes with product, wrap it around the supplied Gyeon Q²M Applicator Block and wipe it evenly on to the first panel, using light pressure and overlapping strokes. Because it contains a fluorinated solvent, Gyeon Q² Booster flashes off very quickly. You should therefore treat a single panel at a time and buff off the haze immediately after. Buffing off is best accomplished with a PB Super Buffing Towel using moderate speed and pressure in order to fully remove the haze and reveal an intense streak-free shine. After all of the panels are treated the car must then be left in a warm, dry place out of direct sunlight for a minimum of 12 hours (24 hours is better) to allow the fluorinated surface layer to cure (if you wish, you can accelerate this process by heating the treated panels to 60°C for 10 minutes using an infra-red heat lamp). Once exposed to the elements, avoid washing the car with any kind of detergent for the first 7 days.
