I have found the super cheap is better than kitten, espiecally when driving on dirt roads( dust doesnt stick to it.), I spray it on, then wipe it with a rag to get rid of any excess, also use it on the bumper and side strip rubbers, normally lasts about a month, but the car is in a carport at home and work, also have used armoural , but its a bit exp to spray on tyres, but great for dash and door rubbers.
