Gentlemen,
I have been looking at used 545i's, and on a couple of cars I've seen this molasses-like looking substance on wheels and brake calipers. Does anyone know what this is? I doesn't look like brake dust to me. Is it anything serious?
Thanks,
Dean

This light brown gooey substance is likely used tire prep gel. I stopped using this because after washing my car this mystery gunk would appear on the sides of my car. It is hard to wash off. Once I stopped using tire shining gel, the problem disappeared.

Are you sure it's not a light coating of oxidation (rust) ?
Not unusual for discs that were wet (via washing or whatever) then not driven right away.
It only takes a day (or less) to show up, and 1 drive to get rid of.
Nothing serious
