This reminds me of one time when my friend plastidipped a penis on my car. I was furious because not only did it happen at a college campus, but he did it because he thought it was funny, and it wasnt. it was embarrassing and it was straight vandalism. i was pretty mad, thus he did it the second time with only this time it was a heart.
At least it was plastidip, so it came off. But needless to say, a lot of people have no idea that the things they do to our cars isn't just a simple fix and I firmly believe that they just do it because they can get away with it and they leave us with the burden of thought of "what might happen next to our cars?"
