Apply Auto Finesse Aqua Coat to transform car washing; this quick and easy solution offers long-term protection, plus superior water beading on all exterior surfaces. Aqua Coat adds a Si02 coating layer while washing, then rinse and spray a fine mist of Aqua coat on the car while still wet. Afterwards, rinse again to experience the instant hydrophobic effects that lasts up to 3 months. Finally, dry your vehicle as usual and the initial coat is complete; top up coats can be added as needed.
