My first post so be kind. I have searched the forum but have not found any threads associated with the care and cleaning of the matte black exhaust. Specifically, I am starting to notice some minor scuff marks. I have been washing with mild car wash soap and drying with chamois and wipe down between washes with micro fiber towels. The minor scuff marks are driving me crazy so after some advice for prevention and possible removal of scufffs and light scratches. Thanks in advance for your advice!
