The particles that come off of your brakes are indeed very hot. Its mainly on the wheel wells (quarter panel) areas. Along with rocker panels and back bumper.
I am very confident that the contrast in temperature from the brake particles versus the painted panels is allowing these particles to easily bond. I never see this in the warm month's. 2 weeks into winter and cold temps, snow, road salt, and its there. I am meticulous with my vehicles and paint was 100%.
You ever hear those snow plows and graders going down the road... blades scraping on the pavement, block after block, mile after mile. I'm always thinking about the number of iron particles left behind. Millions and millions of them-- combined with some melt water and the chemicals they use-- splashed up on the rockers and then drying in the sun or in the garage. We know how much "grit" adheres- we see it. And then we re-wet it next time out. And it often dries again. It's a pretty noxious mix. I would lean toward this being the majority of the cause of adhering iron particles, but hard to know for sure. Dry panels in the summer time (and no "fresh iron" source) would certainly be less prone to particle adhesion.
