Carlack Glass Finish should be applied in a warm, dry, well-ventilated space out of direct sunlight. To protect your skin, we recommend wearing PB Nitrile Gloves during the application process. To achieve the quoted durability and performance benefits, it is necessary to properly clean the surfaces to be treated in advance. To do this, use Carlack Glass Compound to initially cut away any stubbornly bonded surface contaminants, and then use Carlack Glass Clear to remove any lingering grease and grime (put simply, the cleaner the glass is before the sealant is applied, the longer it will last). To apply the sealant, shake the bottle vigorously first to ensure that the contents are fully mixed. Next, lightly wet a Nanolex Cotton Applicator Pad with a few drops of product and work them in to the glass in a circular fashion, using firm pressure. The resulting film should then be left to dry for a minimum of 10 minutes before being buffed off with a PB Utility Towel. If you find the residue difficult to remove, mist the treated surfaces with deionised or distilled water and continue buffing until any haziness disappears.
