This rust spot issue is strange..... I have a white truck and my wheels a larger offset so my tires stick out from the fenders, I get alot of stuff thrown up on my paint, and I get a few small nicks and chips from time to time, and I actually even have a couple little red dots (I assume I ran over something red or wet red paint or something), but never much issue cleaning it off. I was my truck MAYBE once a month at most, and damn near all the spots wipe off(with the exception of any small dings/chips). I really like the white, I think it always seems to look good even when dirty. It never really looks perfectly clean like other colors, but also even when it's really dirty it doesn't look all that dirty. It always looks in between lol.
Breathing in and out is good enough for me.
