Id say its pretty durable. Ive had my wheels p-dipd for about 6 months and theres no scratches or peeling. But they are starting to get a hint of haziness from the brake dust. I havent tried cleaning them but i am planning on spraying them with a few fresh coats to even out some imperfections. My advice is to spray thick layers so its easy to peel off. I doubt Id be able to peel off mine easily right now.
Would it be cheaper to buy plastidip online and get it shipped to you?
