It depends, as weird as it sounds, if you want it to come off and you pick at it it will come off and then peel off. If you spray it and leave it then it stays! I plasti dipped my winter wheels and we have seen salt, snow, rain, dry, sand. Everything and it has not come off. If you curb your wheels though, then it will come off (obviously). The only bad thing is that once brake dust is on there, it is pretty much not going to come off...
