Hey guys,

I detailed my car yesterday and today I already see lots of black dust on my rear bumper. It looks really odd and wonder if anyone else has seen this.

Aside from jetseal (already done) is there anything I can do to keep it off?

Thanks!

It will happen after about 2 minutes of driving. It obviously comes from your exhaust. There's really nothing you can do to prevent it. I just do a quick wipe down with my quick detailer whenever I pull back into the garage.

haha, not so obvious to me!

Thanks

My E90 335i has the same issue. Lots of exhaust residue on the rear.
