Our X looked like this after we went to Joshua Tree last Spring... our's is black and the pin striping looks real bad up close but is invisible from 20 feet away (what they call a 20/20 paint job)... our body and paint guy tells me that they can cut the clear coat and buff out all but the deepest cuts but that you can only do that 4 or 5 times before you start cutting through the paint... he recommends buffing it out once a year (about $200) and then repainting it after 5 years... in the mean time a good cleaning and waxing will cover some of the stripes and you should wear the rest with pride!!!
Does it look like that after you washed it? I have not washed my car yet, so I cannot tell you how many stripes I have... However, since we went through the same trail I suspect that I am in for a surprise
