I have had the wheels on my truck done for over a year. I used two full cans on all four wheels. It has been in mud and done fine. I use a scrub brush and they clean right up. I did the ones on my ATV and it lasted through mud holes that were taillight deep. I ride a Can Am on 30'' tires... The mud holes i ride in are about waist deep. It will stick fine to plastic. its all about the prep work.
