Gyeon Wet Coat 500ml QM WetCoat is a instant, brilliantly easy to use hydrophobicity booster. Its a ready to use formula, giving outstanding results in a simple and quick hydrophobic spray on/rinse off process. It will add great self-cleaning properties to not only the paintwork but also to plastic or metal trims, rims or windows. Make sure the surface is clean before applying. Always apply to a wet surface, one area at a time, and rinse of immediately with high pressure. Do not work large areas at a time.
