Yeah I used plastidip, it depends on how many coats you put on, I did 4-5 coats on everything. I did all my wheels, bumpers, grill and step bars and I think I used 5 cans, maybe 6. I don't do much offroading or anything, so probably not the most hostile environment, but everything is holding up well so far except the step bars. It's been on for 3-4 months now. I've washed it plenty of times, doesn't hurt it. There's a spot on my step bars where I step when loading stuff in the backseat where I step and twist my foot and I wore the pd off of there after about a month or so, but other than that, i think it looks great.

 

You would think that it would be really durable, but ive heard other wise if you dont always drive on the street. But for street use only i would say you could really make it last!
