The little scooters exhaust is a bit rusty and dirty just before the expansion chamber, and it's annoying to look at. What can I do to make it shiny again?
Autosol polish does a great job. I used it to polish up the exhaust tips on our 330D - probably the first/only time that had been done since it left the factory. They were all sooty and rusty beforehand, got them looking like new...
