Ensure you are working in a well ventilated area, out of direct sunlight and wearing gloves. Also ensure temperature is 5c or above. Clean all glass before application using G6 Perfect Glass. For best results use G4 Glass Polish to ensure the glass is perfectly prepped. Shake G1 well and apply a liberal amount to a AP1 Lint Free Applicator. For windscreens we recommend applying 3 layers but only 1 layer on side and rear windows. Work G1 into the glass in circular motions, covering all glass and allow to cure for 5 minutes. Using a new AP1 applicator, apply the same amount of product to the pad, but this time put G1 over your previous layer in a side to side motion, leave for a further 5 minutes to cure. Apply your third layer with the same amount of product on a AP1, however this time apply in vertical straight lines, leave to cure for 15 minutes. Remove cured residue, with G2 Residue Remover. Dab the G2 onto the remaining applicator and apply to a small area at a time, then buff the glass immediately with an MF1 cloth. Finish by cleaning the wiper blades and glass with G6 Perfect Glass and an MF5. We recommend you apply a layer of G1 on your wiper blades without removing residue. If wiper blades are worn they should be replaced. Do not expose your car to the elements for at least 3 hours.
