used tire spray for 20 years. starting with Armor All about NIGRIN to SONAX. which is the best SONAX really. once fed aufgesprayed considers it for weeks, even if sometimes a downpour comes up. klaro, the excess spray spraddelt at high speeds on the paint, but where do the shine come to when there is no material on the tire. I treat the ripe evening and leave the product on overnight. then you have the problem with the pollution of the bodywork also not so much. a super product that holds a great shine for weeks. for vehicles, which are often long and moves at high speeds recommended rather less.
